ABSTRACT

La migraña es una enfermedad que se ha visto asociada a defectos septales auriculares y a su cierre percutáneo, estipulándose en la literatura que sería una rara complicación, pero la evidencia al respecto es escasa. Se realizó una revisión narrativa sobre definiciones, epidemiología, fisiopatología y tratamiento de la migraña y de la entidad migraña poscierre percutáneo de defectos del septum auricular, incluyendo trabajos observacionales (retrospectivos, prospectivos), estudios randomizados, reportes de casos, artículos de revisión y metaanálisis existentes en PubMed y Cochrane, para aportar al conocimiento de esta entidad.


Migraine is a disease that has been associated with atrial septal defects and its percutaneous closure, stipulating in the literature that it would be a rare complication, but evidence is scarce. A narrative review was conducted on definitions, epidemiology, pathophysiology and treatment of migraine and the migraine entity after percutaneous closure of atrial septum defects, including observational studies (retrospective, prospective), randomized studies, case reports, review articles and meta-analyses existing in PubMed and Cochrane, to contribute to the knowledge of this entity.

ABSTRACT

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.

ABSTRACT

Objective: For patients with atrial fibrillation (AF) complicated with acute coronary syndrome (ACS), both anticoagulant and antiplatelet therapy should be applied, but the use of anticoagulation therapy is still poor in these patients in China. The purpose of this study was to explore the status and adherence of antithrombotic therapy in AF patients with ACS and the impact on 1 year clinical outcomes. Methods: Patients with AF hospitalized for ACS were retrospectively included from 6 tertiary hospitals in China between July 2015 and December 2020. According to the use of anticoagulant drugs at discharge, patients were divided into two groups: anticoagulant treatment group and non-anticoagulant treatment group. Logistic regression model was used to analyze the main factors influencing the use of anticoagulant drugs in patients with atrial fibrillation complicated with ACS. Major adverse cardiac events (MACEs) were defined as all-cause death, non-fatal myocardial infarction or coronary revascularization, and ischemic stroke and Bleeding Academic Research Consortium (BARC) 3 bleeding events were also collected at 1 year after discharge. After propensity score matching, Cox proportional hazards models and Kaplan-Meier analysis were used to evaluate the effect of anticoagulant treatment and non-anticoagulant treatment on 1-year prognosis. The patients were divided into different groups according to whether anticoagulation was performed at discharge and follow-up, and the sensitivity of the results was analyzed. Results: A total of 664 patients were enrolled, and 273 (41.1%) were treated with anticoagulant therapy, of whom 84 (30.8%) received triple antithrombotic therapy, 91 (33.3%) received double antithrombotic therapy (single antiplatelet combined with anticoagulant), and 98 (35.9%) received single anticoagulant therapy. Three hundred and ninety-one (58.9%) patients were treated with antiplatelet therapy, including 253 (64.7%) with dual antiplatelet therapy and 138 (35.3%) with single antiplatelet therapy. After 1∶1 propensity score matching between the anticoagulant group and the non-anticoagulant group, a total of 218 pairs were matched. Multivariate logistic regression analysis showed that history of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention were predictors of the absence of anticoagulant therapy, while history of ischemic stroke and persistent atrial fibrillation were predictors of anticoagulant therapy. At 1-year follow-up, 218 patients (79.9%) in the anticoagulant group continued to receive anticoagulant therapy, and 333 patients (85.2%) in the antiplatelet group continued to receive antiplatelet therapy. At 1-year follow-up, 36 MACEs events (13.2%) occurred in the anticoagulant group, and 81 MACEs events (20.7%) in the non-anticoagulant group. HR values and confidence intervals were calculated by Cox proportional risk model. Patients in the non-anticoagulant group faced a higher risk of MACEs (HR=1.802, 95%CI 1.112-2.921, P=0.017), and the risk of bleeding events was similar between the two group (HR=0.825,95%CI 0.397-1.715, P=0.607). Conclusions: History of diabetes, HAS-BLED score≥3, and percutaneous coronary intervention are independent factors for the absence of anticoagulant therapy in patients with AF complicated with ACS. The incidence of MACEs, death and myocardial infarction is lower in the anticoagulant group, and the incidence of bleeding events is similar between the two groups. The risk of bleeding and ischemia/thrombosis should be dynamically assessed during follow-up and antithrombotic regiments should be adjusted accordingly.

ABSTRACT

Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

ABSTRACT

OBJECTIVE@#To establish a machine learning model to predict the risk of early neurological deterioration (END) based on the clinical and laboratory data of patients with acute ischemic stroke (AIS) before intravenous thrombolysis.@*METHODS@#The clinical data of AIS patients who received intravenous thrombolytic with recombinant tissue plasminogen activator (rt-PA) at the Stroke Center of the First Hospital of Qinhuangdao City from January 2019 to July 2022 were retrospectively analyzed. Patients were divided into END group and non-END group according to whether END appeared after intravenous thrombolytic. Clinical data of patients at admission were collected, including demographic characteristics, clinical evaluation, comorbidification, drug use history, laboratory tests, etc. Univariate and multivariate Logistic regression analysis were performed to screen out the independent predictors of the END of AIS patients after intravenous thrombolytic. The study subjects were randomly divided into a training set and a test set in a 7 : 3 ratio. Four machine learning prediction models, including Logistic regression (LR), K-nearest neighbor (KNN), support vector machine (SVM) and random forest (RF), were established based on independent predictors. The receiver operator characteristic curve (ROC curve) was used to evaluate the predictive ability of each model in END.@*RESULTS@#A total of 704 patients were enrolled, of whom 99 were identified as END and 605 as non-END. Univariate and multivariate Logistic regression analysis was used to screen out the National Institutes of Health stroke scale [NIHSS, odds ratio (OR) = 1.049, 95% confidence interval (95%CI) was 1.015-1.082, P = 0.004], systolic blood pressure (OR = 1.013, 95%CI was 1.004-1.022, P = 0.004), lymphocyte percentage (LYM%, OR = 0.903, 95%CI was 0.853-0.953, P < 0.001), platelet to lymphocyte ratio (PLR, OR = 1.007, 95%CI was 1.002-1.014, P = 0.013) were the independent predictors of END in AIS patients after intravenous thrombolysis. The area under the curve (AUC) of LR, KNN, SVM, and RF machine learning models in the test dataset were 0.789 (95%CI was 0.675-0.902), 0.797 (95%CI was 0.685-0.910), 0.851 (95%CI was 0.751-0.952) and 0.809 (95%CI was 0.699-0.919), respectively. The RF model had the highest sensitivity (95.7%). The accuracy (0.736), specificity (72.0%) and AUC of SVM model were the highest, and its overall prediction ability was better than the other three models.@*CONCLUSIONS@#Machine learning models have a potential role in early predicting the risk of END after intravenous thrombolysis in AIS patients, and can provide help in clinical decision-making for intravenous thrombolysis.

En este contexto, en la actualidad ha aumentado el uso de las prótesis valvulares biológicas para su tratamiento y, con ello, surge el dilema del manejo antitrombótico en estos pacientes en términos de prevención de tromboembolias y eventos hemorrágicos. ¿Cuál es el fármaco más efectivo y seguro en el período posoperatorio temprano? ¿Qué antitrombóticos podemos utilizar en el período posoperatorio tardío? ¿Qué estrategia seguimos cuando el paciente presenta otras indicaciones de anticoagulación? El objetivo de esta revisión es valorar la evidencia actual respecto al tratamiento antitrombótico en pacientes portadores de prótesis valvulares biológicas con y sin indicaciones adicionales de anticoagulación.


Heart valve disease is a very common condition in the general population and a considerable percentage of these patients require interventional treatment for their valve disease to mitigate its natural evolution. In this context, the use of biological prosthetic valves for their treatment has now increased, and with this, the dilemma of antithrombotic management in these patients arises, in terms of prevention of thromboembolism and hemorrhagic events. What is the most effective and safe drug in the early postoperative period? What antithrombotics can we use in the late postoperative period? What strategy do we follow when the patient presents other indications for anticoagulation? The objective of this review is to assess the current evidence regarding antithrombotic treatment in patients with biological prosthetic valves with and without additional indications for anticoagulation.

ABSTRACT

BACKGROUND: In those patients who do not have timely access to primary angioplasty, the pharmaco-invasive approach, that is, the use of thrombolysis as a bridging measure prior to the coronary angiography, is a safe alternative. AIM: To describe the features of patients with an acute ST-elevation myocardial infarction (STEMI) treated with a pharmaco-invasive strategy. MATERIAL AND METHODS: Descriptive observational study of 144 patients with mean age of 46 years with STEMI who received a dose of thrombolytic prior to their referral for primary angioplasty at a public hospital between 2018 and 2021. RESULTS: There were no differences the clinical presentation according to the Killip score at admission between thrombolyzed and non-thrombolyzed patients (p = ns). Fifty-three percent of non-thrombolyzed patients were admitted with an occluded vessel (TIMI 0) compared with 27% of thrombolyzed patients (p < 0.001). The thrombolyzed group required significantly less use of thromboaspiration (3.5 and 8.4% respectively; p = 0.014). Despite this, 91 and 92% of non-thrombolyzed and thrombolyzed patients achieved a post-angioplasty TIMI 3 flow. Long-term survival was 91 and 86% in thrombolyzed and non-thrombolyzed patients, respectively (p = ns). CONCLUSIONS: The pharmaco-invasive strategy is a safe alternative when compared to primary angioplasty in centers that don't have timely access to Interventional Cardiology.

ABSTRACT

Abstract Objective The present study describes the preferences and current practices of a sample of knee surgeons in Brazil regarding thromboprophylaxis in total knee arthroplasty (TKA). Method In the present internet survey, surgeons from the Brazilian Knee Surgery Society (SBCJ, in the Portuguese acronym) voluntarily answered an anonymous questionnaire including time of personal surgical experience, perceptions about the best thromboprophylaxis options, and actual practices in their work environment. Results From December 2020 to January 2021, 243 participants answered the questionnaire. All, except for 3 (1.2%), reported using thromboprophylaxis, and most (76%) combined pharmacological and mechanical techniques. The most prescribed drug was enoxaparin (87%), which changed to rivaroxaban (65%) after discharge. The time of thromboprophylaxis initiation varied according to the length of training of the knee surgeon (p ≤ 0.03), and their preferences and practices differed according to the Brazilian region (p< 0.05) and the health system in which the surgeons work (public or private sector; p= 0.024). The option for mechanical thromboprophylaxis also depended on the training time of the surgeon. Conclusion Thromboprophylaxis preferences and practices in TKA are diverse across Brazilian regions and health systems (public or private sectors). Given the lack of a national clinical guideline, most orthopedists follow either their hospital guidelines or none. The mechanical prophylaxis method and the little use of aspirin are the points that most diverge from international guidelines and practices.


Resumo Objetivo Descrever as preferências e práticas atuais de uma amostra de cirurgiões de joelho do Brasil quanto à forma de tromboprofilaxia na artroplastia total do joelho (ATJ). Método presente pesquisa realizada pela internet, cirurgiões associados à Sociedade Brasileira de Cirurgia do Joelho (SBCJ) foram convidados a responder voluntariamente a um questionário anônimo incluindo o tempo de experiência cirúrgica pessoal, percepções sobre as melhores opções de tromboprofilaxia e as reais práticas no ambiente onde trabalham. Resultados Entre dezembro de 2020 e janeiro de 2021, 243 participantes responderam ao questionário completo. Exceto por 3 (1,2%) participantes, todos declararam praticar tromboprofilaxia, a maioria (76%) combinando as formas farmacológica e mecânica. A droga mais prescrita é a enoxaparina (87%), com modificação para rivaroxabana (65%) após a alta. O momento de início da tromboprofilaxia variou conforme o tempo de formação do cirurgião de joelho (p ≤ 0,03) e as preferências e práticas variaram conforme a região do país (p< 0,05) e o sistema de saúde no qual trabalham os cirurgiões (público ou privado; p= 0,024). A opção por tromboprofilaxia mecânica também dependeu do tempo de formação do cirurgião. Conclusão As preferências e práticas de tromboprofilaxia na ATJ são diversas nas regiões do Brasil e sistemas de saúde (público ou privado). Dada a inexistência de uma diretriz clínica nacional, a maior parte dos ortopedistas segue ou a diretriz de seu próprio hospital ou nenhuma. O método de profilaxia mecânica e a pouca utilização do ácido acetilsalicílico são os pontos que mais destoam das diretrizes e práticas internacionais.

ABSTRACT

La cardiopatía isquémica es un padecimiento que se caracteriza por la falta de oxígeno del músculo cardiaco y es la principal causa de infarto de miocardio. Existen múltiples factores que predisponen al desarrollo de ésta como la obesidad, la hiperlipidemia, el sedenta- rismo, tabaquismo, diabetes e hipertensión. Dadas las características que configuran la fisiopatología de la cardiopatía isquémica, existen diversas consideraciones que deben ser tomadas en cuenta toda vez que el estomatólogo brinde atención a un paciente con este padecimiento. El objetivo del presente artículo es conocer todo lo relacionado con la fisiopatología de la cardiopatía isquémica, sus manifestaciones clínicas, su tratamiento médico y lo más importante, las consideraciones que deben tomarse en el consultorio dental cuando se atienda a un paciente que padezca esta condición (AU)


Ischemic heart disease is a condition characterized by a lack of oxygen in the heart muscle and is the main cause of myocardial infarction. There are multiple factors that predispose to the development of this, such as obesity, hiyperlipidemia, sedentary lifestyle, smoking, diabetes and hypertension. Given the characteristics that make up the pathophysiology of ischemic heart disease, there are various considerations that must be taken into account whenever the stomatologist provides care to a patient with this condition.

ABSTRACT

Abstract ST elevation myocardial infarction (STEMI) is a highly prevalent condition worldwide. Reperfusion therapy is strongly associated with the prognosis of STEMI and must be performed with a high standard of quality and without delay. A systematic review of different reperfusion strategies for STEMI was conducted, including randomized controlled trials that included major cardiovascular events (MACE), and systematic reviews in the last 5 years through the PRISMA ( Preferred Reporting Items for Systematic Reviews and Meta-Analysis) methodology. The research was done in the PubMed and Cochrane Central Register of Controlled Trials databases, in addition to a few manual searches. After the exclusion criteria were applied, 90 articles were selected for this review. Despite the reestablishment of IRA patency in PCI for STEMI, microvascular lesions occur in a significant proportion of these patients, which can compromise ventricular function and clinical course. Several therapeutic strategies - intracoronary administration of nicorandil, nitrates, melatonin, antioxidant drugs (quercetin, glutathione), anti-inflammatory substances (tocilizumab [an inhibitor of interleukin 6], inclacumab, P-selectin inhibitor), immunosuppressants (cyclosporine), erythropoietin and ischemic pre- and post-conditioning and stem cell therapy - have been tested to reduce reperfusion injury, ventricular remodeling and serious cardiovascular events, with heterogeneous results: These therapies need confirmation in larger studies to be implemented in clinical practice

ABSTRACT

Background:Type 2 Diabetes Mellitus is a disease of epidemic proportions and many patients are at a great risk of premature mortality and complication of atherothrombotic disorders affecting coronary, cerebral and peripheral arterial trees. Increased Plasminogen Activator Inhibitor Type 1 inhibits fibrinolysis and predicts cardiovascular risk in those living with Type 2 Diabetes. This study aimed to determine the effect of antidiabetic treatment on haemostatic and fibrinolytic parameters among Type 2 Diabetic subjects in Ilorin.Methods:This was a comparative cross-sectional study involving 78 Type 2 diabetic patients, (39 treatment naïve, 39 treatment experienced). Full blood count was performed using Sysmex XP300 while Prothrombin time was determined using one stage test of Owren. Activated partial thromboplastin time was determined by method of Proctor and Rapaport. Fibrinogen and Plasminogen Activator Inhibitor type-1 were assayed using AssayMax Human Fibrinogen ELISAand AssayMax Human PAI-1 ELISAkit. Data Analysis was done using SPSS version 25.0.Results:Mean PAI-1 levels were significantly higher in treatment naïve diabetics when compared to treatment experienced diabetics (2.44 ±2.57 vs 2.51±1.47 ng/ml p=0.002) as were fibrinogen levels (434.65±366.15 vs 482.24± 299.64mg /dl; p = 0.048). PAI -1 levels were lowest among diabetics treated with Metformin + DPP4 inhibitors, while fibrinogen levels were lowest among those treated with Metformin + sulfonylurea combination.Conclusion:Oral hypoglycaemic treatment, combination therapy in particular, improves fibrinolysis in type 2 diabetics thereby reducing the risk of cardiovascular disease in type 2 diabetes mellitus patients

ABSTRACT

ABSTRACT BACKGROUND: Peripheral arterial disease (PAD) is characterized by progressive narrowing of the arterial lumen, resulting from atherosclerotic plaques. Treatment for PAD aims to control atherosclerosis and improve blood flow. Use of antiplatelet agents and anticoagulants has played important roles in helping to prevent occlusions and stenosis. OBJECTIVE: To evaluate the evidence from Cochrane systematic reviews regarding the accuracy, effectiveness and safety of use of anticoagulants and antiplatelets in lower-limb revascularization, in patients with peripheral arterial disease. METHODS: Systematic reviews found through searches in the Cochrane Library were included. Two authors evaluated whether the reviews found were in line with the inclusion criteria for this investigation. A qualitative synthesis of their findings was presented. RESULTS: Three systematic Cochrane reviews were included. Patients who underwent prosthetic bypass surgery probably presented greater benefit from use of antiplatelets, and patients who underwent vein revascularization probably presented greater benefit from use of anticoagulants. Patients who received endovascular treatment benefited from both antiplatelet and anticoagulant treatment. However, the reliability of the results found was impaired because at the time when these reviews were published, there was no mandatory assessment using the GRADE criteria. CONCLUSION: Despite the evidence found, it is necessary for these reviews to be updated in order to evaluate the degree of certainty of the results found.

ABSTRACT

Resumen El accidente cerebrovascular (ACV) es una urgencia tiempo dependiente, ya que las conductas de mayor impacto pronóstico dependen del tiempo trascurrido. El objetivo de este trabajo fue analizar nuestros tiempos puerta aguja (TPA), comienzo aguja (TCA) y el efecto que tiene sobre estos el sistema preaviso y la elección adecuada del centro asistencial. Se realizó un estudio observacional con datos obtenidos de histo rias clínicas de pacientes internados en la unidad de ACV. Analizamos el número de tratamientos trombolíticos endovenosos, entre agosto 2015 y diciembre 2019. Comparamos TPA según utilización de pre-aviso, llegada directa por sus propios medios vs. en ambulancia sin pre-aviso, y TCA según llegada directa al centro con unidad de ACV vs. llegada a otro centro para posterior derivación. De 265 pacientes en ventana terapéutica, se realizó tratamiento en 143. Llegaron 137 pacientes derivados de otro centro, 70 recibieron tratamiento trombolítico. El TPA con sistema preaviso y sin preaviso fue 41 ± 23 (media ± DE) y 81 ± 43 minutos, respectivamente (p = 0.001). El TPA con llegada directa por sus propios medios 79 ± 43 y en ambulancia sin preaviso 84 ± 44 minutos (p = 0.7) a unidad de ACV. El TCA en llegada directa a unidad de ACV fue 159 ± 59 y a otro centro para su derivación 199 ± 44 minutos (p = 0.001). La utilización de un sistema de preaviso y la elección directa de un centro con unidad de ACV son medidas clave para reducir los tiempos de tratamiento.


Abstract Acute ischemic stroke (AIS) is a time-dependent emergency, since the greatest impact depends on the time elapsed to treatment. The objective of this work was to analyze door to needle (DTN) and start treatment (STT) times and the effect of pre-notification system (PNS) and the appropriate choice of the healthcare center on these variables. An observational study with data obtained from records of patients admitted to the Stroke Unit (SU) was conducted between August 2015 to December 2019. We analyzed the number of intravenous thrombolytic treatments (IVT), DTN and STT and compared them according to PNS use, direct arrival at the center with SU or arrival at another center for subsequent referral. An overall of 472 patients were hospitalized during the studied period and the treatment was performed in 143 out of 265 patients. One hundred thirty-seven patients arrived from another center, 70 received IVT. Average DNT with PNS and without PNS were 41 ± 23 and 81 ± 44 minutes, respectively (p = 0.001). STT on direct arrival to SU was 159 ± 59 minutes and to another center for referral was 199 ± 44 (p = 0.001). The use of a PNS and the direct choice of a center where IVT is performed significantly improve treatment

ABSTRACT

ABSTRACT BACKGROUND: In July 2012, the Japan Gastroenterological Endoscopy Society updated their guidelines for gastroenterological endoscopy in patients receiving antithrombotic therapy. Colonoscopic polypectomy procedures are associated with a high risk of bleeding. OBJECTIVES: The present study evaluated the safety of colonoscopic polypectomy procedures in terms of bleeding, among patients receiving antithrombotic therapy. DESIGN AND SETTING: Prospective observational study conducted in a tertiary-level public cardiovascular hospital in Istanbul, Turkey. METHODS: Colonoscopic polypectomies carried out in a single endoscopy unit between July 2018 and July 2019 were evaluated prospectively. The patients' data, including age, gender, comorbidities, whether antithrombotic drug use was ceased or whether patients were switched to bridging therapy, polyp size, polyp type, polyp location, histopathology, resection methods (hot snare, cold snare or forceps) and complications relating to the procedures were recorded. RESULTS: The study was completed with 94 patients who underwent a total of 167 polypectomy procedures. As per the advice of the physicians who prescribed antithrombotic medications, 108 polypectomy procedures were performed on 60 patients without discontinuing medication and 59 polypectomy procedures were performed on 34 patients after discontinuing medication. The age, gender distribution and rate of bleeding did not differ significantly between the patients whose medication was discontinued and those whose medication was continued (P > 0.05). CONCLUSION: This study found that the colonoscopic polypectomy procedure without discontinuation of antithrombotic medication did not increase the risk of bleeding. This procedure can be safely performed by experienced endoscopists in patients with an international normalized ratio (INR) below 2.5.

ABSTRACT

Resumen Introducción: Los antagonista de la vitamina K (AVK) son una alternativa terapéutica en los pacientes con enfermedad tromboembólica venosa; sin embargo, numerosos factores afectan su farmacología. Objetivo: Evaluar la calidad de la anticoagulación AVK durante tres diferentes periodos en México. Métodos: Estudio prospectivo, anidado en cohortes de pacientes en tres escenarios clínicos entre los años 2013-2019. Se incluyeron pacientes no hospitalizados con indicación para recibir AVK por al menos 12 meses, quienes fueron manejados de acuerdo con el criterio del médico tratante. Resultados: Las características generales de los pacientes fueron similares entre los grupos, excepto por la indicación para usar los AVK. Se analizaron los resultados de 4148 pacientes y 38 548 evaluaciones de INR. Los tiempos en rango terapéutico durante las tres fases del estudio y los datos acumulados fueron significativamente mayores en la clínica de anticoagulación. Solo el número de visitas de control de los pacientes se asoció significativamente con los resultados, a diferencia de la edad, el sexo y el tipo de AVK. Conclusiones: Los AVK se utilizan ampliamente, pero es difícil alcanzar la meta terapéutica, sobre todo en servicios clínicos no especializados. La creación de clínicas de anticoagulación es una necesidad urgente en el sistema mexicano de salud.


Abstract Introduction: Vitamin K antagonists (VKA) are a therapeutic alternative in patients with venous thromboembolic disease; however, numerous factors affect their pharmacology. Objective: To evaluate the quality of VKA anticoagulation at three different time periods in Mexico. Methods: Prospective study, nested in patient cohorts at three different clinical scenarios between 2013 and 2019. Outpatients with indication for treatment with VKAs for at least 12 months were included. Patients were managed according to the criteria of the treating physician. Results: Patient general characteristics were similar between groups, except for the VKA indication. The results of 4,148 patients and 38,548 INR assessments were analyzed. The times in therapeutic range during the three phases of the study and pooled data were significantly higher for the anticoagulation clinic. Only the number of patient visits was significantly associated with the results, unlike age, gender, and type of VKA. Conclusions: VKAs are widely used, but it is difficult for therapeutic goals to be achieved, especially in non-specialized clinical services. Creation of anticoagulation clinics is an urgent need for the Mexican health system.

ABSTRACT

Resumen Se realizó un estudio unicéntrico retrospectivo para evaluar la eficacia y seguridad de trombolisis dirigida por catéter (TDC) en pacientes con tromboembolismo pulmonar agudo (TEP) de 2014 a 2020. Se analizó la efectividad (mejoría de presión pulmonar), y seguridad (sangrado intracraneal y grave definido por compromiso hemodinámico). Se incluyeron 43 pacientes, de 67(56-79) años, 5 (12%) con shock, 41 (95%) con dilatación del ventrículo derecho y TEP bilateral. La decis ión de TDC fue: tratamiento inicial (53%), escalada de anticoagulación (42%) y rescate de trombolisis sistémica (5%). Se utilizó TDC facilitada por ultrasonido en 40 casos (93%), utilizándose 30 (25-35) mg de activador tisular del plasminógeno recombinante (rtPA) durante 20 h. Se administró un bolo de rtPA en 38 (89%) casos, que fue 5 mg (95%) o 1 mg (5%). Se utilizó un solo catéter por paciente. En 4 (9%) se decidió recolocación (mismo pulmón) para continuar infusión en otro sector. Se observó una disminución significativa de la presión media pulmonar (pre 35 [29-41] mmHg vs. post 24 [20-34] mmHg, p<0.001). No se observó ningún caso de hemorragia intracraneal, y un caso (2%) de sangrado grave. Se observó hematoma del sitio de punción en 5 (12%) (incluyendo el sangrado grave), y requirió transfusiones en 3 (7%). La mortalidad intrahospitalaria fue 12%, siendo un solo c aso (2%) atribuido al TEP. El tratamiento con TDC fue efectivo asociándose a una reducción significativa de la presión pulmonar, sin observarse ningún sangrado intracraneal y con un sangrado grave. Nuestros resultados se asemejan a lo publicado en otros estudios.


Abstract We performed a single center retrospective study in patients with pulmonary embolism (PE) undergoing catheter directed thrombolysis (CDT) from 2014 to 2020. Efficacy was defined by mean pulmonary pressure drop, and safety was assessed by intracranial and severe bleeding (defined by GUSTO). Forty-three patients were included, aged 64 (56-79) years old, 5 (12%) with shock, most with right ventricle dilation (95%) and bilateral PE (95%) or unilateral (5%) in patients with only one functional lung. CDT was used as first treatment (53%), upscale after anticoagulation alone (42%), or after failed systemic thrombolytics (5%). Median recombinant tissue plasminogen activator (rtPA) dose was 30 (25-35) mg over 20 (20-20) hours, and rtPA bolus was used after catheter placement in 38 cases (89%), consisting of 5 mg (95%) or 1 mg (5%). Only one lung was treated for technical reasons, and 4 (9%) were repositioned in the same lung for continuation of infusion. A significant reduction in mean pulmonary pressure was observed (pre 35 [29-41] mmHg vs. post 24 [20-34] mmHg, p<0.001) with no intracranial bleeding. One patient (2%) experienced severe bleeding, while 5 (12%) presented access site bleeding, and 3 (7%) required blood transfusions. In-hospital mortality was 12% but only one case (2%) due to PE. Our results are similar to previously reported studies.

ABSTRACT

Resumen La fibrinólisis intravenosa con activador del plasminógeno tisular recombinante (rTPA) y la utilización de unidades cerradas, demostraron disminuir sustancialmente la morbimortalidad en pacientes con accidente cerebrovascular isquémico (ACVi). Sin embargo, los datos publicados en Argentina son escasos. Describimos la experiencia en la utilización de fibrinólisis en pacientes con ACVi agudo antes y después de la implementación de una unidad cerebrovascular (UCV) en un Centro Integral de Neurología Vascular de la Ciudad de Buenos Aires durante 17 años. Se realizó un análisis retrospectivo de pacientes consecutivos tratados con rTPA entre enero 2003 y diciembre 2019. Se evaluaron tiempos de tratamiento, de internación, complicaciones post tratamiento y discapacidad a 3 meses. Para su análisis se evaluaron los períodos pre y post apertura de la UCV, período 1 (P1 de 2003-2011) y P2 (2012 -2019). Se realizó fibrinolisis intravenosa en 182 pacientes. La apertura de UCV resultó en aumento del porcentaje de fibrinólisis sobre el total de los ACVi ingresados (4% en P1 vs. 10% en P2, p < 0.001), acortamiento del tiempo puerta-aguja (75 minutos en P1 vs. 53 minutos en P2, p < 0.00001) y mayor proporción de pacientes tratados dentro de los 60 minutos del ingreso hospitalario (36% en P1 vs. 76% en P2, p < 0.00001). Además, hubo reducción de la mediana de internación de 9 días en P1 a 5 días en P2 (p < 0.00001). En conclusión, la UCV parece optimizar la utilización de fibrinólisis en el ACVi agudo, aumentando el porcentaje de pacientes tratados, reduciendo el tiempo puerta-aguja y disminuyendo el de internación.


Abstract Intravenous fibrinolysis with recombinant tissue plasminogen activator (rTPA) and use of stroke units improve morbidity and mortality in patients with acute ischemic stroke (AIS). However, data published in Argentina are scarce. We describe the experience in the use of fibrinolysis in patients with acute ischemic stroke (AIS) before and after the implementation of a stroke unit in a Comprehensive Stroke Center in Buenos Aires during the last 17 years. Retrospective analysis of consecutive patients treated with rTPA between January 2003 and December 2019. Treatment times, hospitalization time, post-treatment complications and disability at 3 months were evaluated. For the analysis, the pre and post opening periods of the stroke unit were evaluated, Period 1 (P1, from 2003 to 2011) and Period 2 (P2, from 2012 to 2019). Intravenous fibrinolysis was performed in 182 patients. Opening of the stroke unit resulted in an increase in the percentage of fibrinolysis over the total number of admitted strokes (4% in P1 vs. 10% in P2, p < 0.001), shortening of the door-to-needle time (75 minutes in P1 vs. 53 minutes in P2, p < 0.00001) and higher proportion of patients treated within 60 minutes of hospital admission (36% in P1 vs. 76% in P2, p < 0.00001). In addition, there was a reduction in the median hospital stay from 9 days in P1 to 5 days in P2 (p < 0.00001). In conclusion, stroke units seem to optimize the use of fibrinolysis in acute stroke, increasing the percentage of patients treated, reducing door-to-needle time, and reducing hospitalization time.
