Serial values of hematologic variables and deep venous thrombosis: Red cell distribution width is associated with deep venous thrombosis

Abstract Introduction As 30 to 50% of deep venous thrombosis (DVT) cases remain idiopathic, an increased focus on hematologic variables may therefore reveal novel correlates of DVT. Very few studies have investigated the association of hematological parameters with DVT and the causal relationship between them is still to be elucidated. Therefore, we aimed to investigate the association between serial values of hematologic variables and DVT. Methods Complete blood count parameters were serially measured at baseline and then at approximately 3-month intervals for 12 months in 152 adults with the first episode of DVT and 152 age- and sex-matched controls. The odds ratio (OR) with the 95% confidence interval (95%CI) was calculated as a measure of association between hematological parameters and DVT. Results The red cell distribution width (RDW) was the only hematologic variable which showed an independent and consistent association with DVT at all time points (multivariable-adjusted OR [95%CI] 3.38 [1.28 - 8.91] at baseline, 2.24 [0.85 - 5.92] at 3 months and 2.12 [0.81 - 5.55] at 12 months for RDW > 14.0%). This association was higher for provoked DVT than unprovoked DVT and for DVT plus pulmonary embolism than DVT alone. No significant correlation was found between the high RDW and classical thrombotic risk factors, except malignancy. Conclusions We demonstrated an independent and consistent association of the high RDW with the first episode of DVT in adult patients. The study was probably underpowered to evaluate the association between the high RDW and recurrent DVT. Further large studies with long follow-up are needed to confirm this association.

Cardiovascular events associated with thalidomide and prednisone in leprosy type 2 reaction

Abstract Background: Thalidomide is the drug of choice for the treatment of type 2 leprosy reactions and is often associated with corticosteroids. The use of these drugs in multiple myeloma is associated with the risk of cardiovascular events, but there have been few studies assessing this risk in leprosy patients. Objective: To evaluate the occurrence of cardiovascular events in patients with multibacillary leprosy and their correlation with the use of thalidomide and prednisone. Methods: Analytical cross-sectional study of all patients diagnosed with multibacillary leprosy treated at the Dermatology Service between 2012 and 2022, using electronic medical records. Thromboembolic vascular events, both arterial and venous, including acute myocardial infarction, were considered. The main independent variable was the concomitant use of thalidomide and prednisone during follow-up. Results: A total of 89 patients were included, of which 19 used thalidomide and prednisone concomitantly. There were five cardiovascular events (26.3%), three of which of deep venous thrombosis. The combined use of medications was associated with the events (PR = 6.46 [3.92 to 10.65]; p<0.01). Study limitations: Small number of events, single-center retrospective study. Conclusion: The hypothesis of an association between cardiovascular events and the concomitant use of thalidomide and prednisone is supported, but more robust prospective studies are required for a better assessment.

SUMMARY Objective To determine whether an educational intervention strategy would improve the frequency of medical prescriptions for adequate thromboprophylaxis in a medicine service. Methods Quasi-experimental study, in which in the pre-intervention phase the frequencies of indication of appropriate thromboprophylaxis by physicians from the medicine service were obtained. An 8-week educational intervention was carried out with this same group of doctors. In the post-intervention phase, the frequency of adequate thromboprophylaxis was measured at 2 and 4 months after the intervention. Results The educational intervention was implemented in 112 resident physicians in medicine specialties. All prescriptions were made by the first-year resident physicians and endorsed by their supervising physician. Prior to the intervention, 47 (44.35%) adequate prescriptions were obtained, 13 (12.26%) suboptimal, 4 (3.77%) inadequate, and 42 (39, 62%) no prescription. After the intervention, the following 2 months were obtained: 78 (75.72%) adequate prescriptions, 7 (6.79%) suboptimal, 4 (2.91%) inadequate and 15 (14.58%) no prescriptions, there being a significant difference with the baseline level. At the subsequent 4 months post-intervention, the following were obtained: 86 (83.49%) adequate, 5 (4.85%) suboptimal, 2 (1.94%) inadequate and 10 (9.72%) no prescription, with a difference significant with the baseline level. There was no increase in the frequency of overuse. Conclusions The application of an educational strategy to medical personnel was effective in increasing correctly indicated thromboprophylaxis prescriptions in a medical service. No overuse of thromboprophylaxis was found after the intervention.

Biological identity of orbital cavernous venous malformations

ABSTRACT Vascular anomalies comprise a wide spectrum of clinical manifestations related to disturbances in the blood or lymph vessels. They correspond to mainly tumors (especially hemangiomas), characterized by high mitotic activity and proliferation of the vascular endothelium, and malformations, endowed with normal mitotic activity and no hypercellularity or changes in the rate of cell turnover. However, the classifications of these lesions go beyond this dichotomy and consist various systems adapted for and by different clinical subgroups. Thus, the classifications have not reached a consensus and have historically caused confusion regarding the nomenclatures and definitions. Cavernous venous malformations of the orbit, previously called cavernous hemangiomas, are the most common benign vascular orbital lesions in adults. Herein, we have compiled and discussed the various evidences, including clinical, radiological, morphological, and molecular evidence that indicate the non-neoplastic nature of these lesions.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: Anemia tolerance mechanisms

Abstract Understanding the physiological concepts of oxygen delivery is essential to discern the mechanisms that influence its increase, reduction or maintenance in the body. This text explores the different mechanisms that help maintain oxygen delivery even in the face of reduced hemoglobin levels. Adequate oxygen delivery ensures tissue and metabolic balance, which is crucial to avoid harmful consequences such as metabolic acidosis and cellular dysoxia. The complex interaction between variables such as cardiac output, hemoglobin and heart rate (HR) plays a fundamental role in maintaining oxygen delivery, allowing the body to temporarily adjust to situations of anemia or high metabolic demand. It is important to emphasize that blood transfusions should not be based on fixed values, but rather on individual metabolic needs. Strategies to reduce myocardial consumption and monitor macro and micro hemodynamics help in making rational decisions. Individualizing treatment and considering factors such as blood viscosity in relation to the benefits of transfusion are increasingly relevant to optimize therapy and minimize risks, especially in complex clinical scenarios, such as neurocritical patients and trauma victims.

A mudança de paradigma no tratamento do tromboembolismo venoso grave / The paradigm shift in treatment of severe venous thromboembolism

Resumo A embolia pulmonar (EP) é a terceira maior causa de morte cardiovascular e a principal de morte evitável intra-hospitalar no mundo. O conceito PERT® (do inglês, pulmonary embolism response team) envolve seu diagnóstico e tratamento precoce e multidisciplinar. A trombose venosa profunda (TVP) é a sua causa inicial na maioria dos casos e é responsável por complicações como a recidiva tromboembólica, a síndrome pós-trombótica e a hipertensão pulmonar tromboembólica crônica. Uma abordagem inicial semelhante ao PERT nos casos de TVP ilíaco-femoral grave pode reduzir não apenas o risco imediato de EP e morte, mas também suas sequelas tardias. Novas técnicas percutâneas e aparatos de trombectomia mecânica para o tromboembolismo venoso (TEV) vêm demonstrando resultados clínicos encorajadores. Propomos o desenvolvimento de um conceito ampliado de resposta rápida ao TEV, que envolve não apenas a EP (PERT®) mas também os casos graves de TVP: o time de resposta rápida para o TEV (TRETEV®), ou do inglês Venous Thromboembolism Response Team (VTERT®).

Abstract Pulmonary embolism (PE) is the third leading cause of cardiovascular death and the main cause of preventable in-hospital death in the world. The PERT® (Pulmonary Embolism Response Team) concept involves multidisciplinary diagnosis and immediate treatment. Deep venous thrombosis (DVT) is the initial cause of most cases of PE and is responsible for complications such as chronic thromboembolic recurrence, postthrombotic syndrome, and chronic thromboembolic pulmonary hypertension. An aggressive approach to severe cases of iliofemoral DVT similar to the PERT® system can not only reduce the immediate risk of PE and death but can also reduce later sequelae. New percutaneous techniques and mechanical thrombectomy devices for venous thromboembolism (VTE) have shown encouraging clinical results. We propose the development of an expanded concept of rapid response to VTE, which involves not only PE (PERT®) but also severe cases of DVT: the Venous Thromboembolism Response Team (VTERT®).

Portal vein thrombosis in liver cirrhosis： Risk factors and protection strategies / 临床肝胆病杂志

Portal vein thrombosis （PVT） is one of the common complications during the natural course of liver cirrhosis and has an important influence on the progression of liver cirrhosis. This article mainly summarizes the research advances in the risk factors for PVT. There are many risk factors for PVT， and Virchow’s triad， namely venous stasis， hypercoagulability， and vascular endothelial injury and systemic inflammation caused by surgery or trauma， are considered the main reasons for the development and progression of PVT. At present， more prospective studies are still needed to validate the predictive models for the risk of PVT that have certain application prospects in clinical practice. Cirrhotic patients with PVT tend to have a poor prognosis， and complete obstructive PVT is associated with increased mortality after liver transplantation. Recent studies have shown that prophylactic anticoagulant therapy is safe and effective in patients with liver cirrhosis and can thus help with the prevention and treatment of PVT.

Screening for the etiology of non-cirrhotic splanchnic vein thrombosis should be taken seriously in clinical practice / 临床肝胆病杂志

Non-cirrhotic splanchnic vein thrombosis （NC-SVT） mainly includes portal vein thrombosis， superior mesenteric vein thrombosis， splenic vein thrombosis， and hepatic vein thrombosis （Budd-Chiari syndrome）， and its prevalence rate is increasing with the increase in the incidence rates of related underlying diseases. Due to the harm of NC-SVT， there have been significant improvements in the awareness and ability for diagnosis among clinicians. However， anticoagulation and intervention therapies for thrombosis are often taken seriously in treatment， while the screening for risk factors or underlying diseases leading to SVT is ignored， which may affect the treatment outcome of thrombus in some patients and delay the diagnosis and treatment of the underlying disease. This article mainly introduces the acquired， hereditary， systemic， and local underlying diseases associated with the development of NC-SVT.

Systemic Hormonal Unloading (SHU) in secondary hypertension: Addressing the long-term adverse cardiovascular outcomes

@#Excess hormone production from adrenal tumors caused by primary hyperaldosteronism or pheochromocytoma are common etiologies for secondary hypertension. Studies have shown that sustained long-term circulating hormones in excess affect the blood vessels and cardiac structures. Inflammation of cardiomyocytes leads to fibrosis and eventual cardiomyopathy and is clinically presented as arrhythmia, nonfatal myocardial infarction, heart failure, or even death. The tissue changes and/or impaired cardiac function are reversible if early diagnosis and removal of the adrenal tumor by unilateral adrenalectomy is done. However, the condition becomes challenging if the adrenal lesions are bilateral. This article introduces the concept of systemic hormonal unloading and will discuss the philosophy of quality of life in managing bilateral adrenal disease.

Cerebral venous sinus thrombosis presenting as intracerebral hemorrhage and subarachnoid hemorrhage: A case report

@#We present a 66-year-old male presenting with sudden onset of headache. Medical decompression was done and neuroimaging of plain cranial CT angiogram (CTA) and CT venogram (CTV) showed components of subarachnoid hemorrhage, intracerebral hemorrhage and hyperdense appearance of the superior sagittal sinus and proximal left transverse sinus. The following were done to look for etiologic factors: 1. fungal swab to determine the cause of the intracerebral hemorrhage secondary to venous thrombosis as the patient presented with a chronic history of sinusitis, 2. coagulopathy workup to look for a hypercoagulable state, and 3. workup for systemic disease of autoimmune in etiology. Anticoagulation was safely initiated within several days given the regression of the intracerebral hemorrhage along with stable findings of subarachnoid hemorrhage. Here we report cerebral venous sinus thrombosis rarely presenting as acute subarachnoid hemorrhage and intracerebral hemorrhage.

Meta-analysis of the efficacy and safety of novel oral anticoagulants in the treatment of venous thromboembolism in cancer patients / 中国药房

OBJECTIVE To systematically evaluate the efficacy and safety of novel oral anticoagulants （NOAC） in the treatment of cancer-related venous thromboembolism （VTE） patients. METHODS Retrieved from PubMed， Cochrane Library， Embase， Web of Science， CNKI， and Wanfang database from the establishment of each database to August， 2023， randomized controlled trials （RCTs） about the efficacy of low-molecular-weight heparin （LMWH， control group） versus NOAC （trial group） in the treatment of cancer-related VTE patients were collected. After extracting the data from included clinical studies， meta-analysis was performed by using RevMan 5.0 statistical software. RESULTS A total of 7 RCTs were included， with a total of 3 790 patients. Compared with the control group， the recurrence rate of VTE in the trial group was significantly reduced （RR＝0.65， 95%CI 0.51-0.82， P＝0.000 4）， while the incidence of major bleeding was slightly higher than in the control group， but the difference was not statistically significant （RR＝1.13， 95%CI 0.83-1.53， P＝0.45）. The incidence of clinically relevant non-major bleeding （RR＝1.69， 95%CI 1.34-2.13， P＜0.000 01） and gastrointestinal bleeding （RR＝1.96， 95%CI 1.15-3.34， P＝0.01） in the trial group was significantly higher than in the control group. There was no statistically significant difference in the incidence of intracranial hemorrhage， all-cause mortality， and fatal pulmonary embolism between 2 groups （P＞0.05）. CONCLUSIONS For cancer-related VTE patients， NOAC is superior to LMWH in preventing venous thrombosis recurrence， and is not inferior to LMWH in terms of major bleeding， intracranial hemorrhage， all-cause mortality， and fatal pulmonary embolism.

Correlation between lung allocation score and early death risk of patients with idiopathic pulmonary fibrosis after lung transplantation / 器官移植

Objective To analyze the correlation between the lung allocation score (LAS) and the risk of early death and complications in patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 275 patients with IPF were retrospectively analyzed. The correlation between LAS and the risk of early death in IPF patients after lung transplantation and the correlation between LAS and complications at postoperative 1 year was assessed by univariate and multivariate Cox regression analyses. Results Among 275 recipients, 62, 83, 95 and 108 cases died within postoperative 30, 90, 180 and 365 d, respectively. LAS was correlated with 30-, 90-, 180- and 365-d fatality of IPF patients (all P<0.05), whereas it was not correlated with the incidence of primary graft dysfunction (PGD) and acute kidney injury (AKI) at 365 d after lung transplantation (both P>0.05). Conclusions LAS is correlated with the risk of early death of IPF patients after lung transplantation. While, it is not correlated the incidence of PGD and AKI early after lung transplantation. Special attention should be paid to the effect of comprehensive factors upon PGD and AKI.

Treatment options for hemodialysis-related central vein occlusive disease: Case series and review of literature

Majority of cases are related to central venous catheter placement. This paper reports on three patients on chronic hemodialysis who presented with signs and symptoms of upper extremity venous hypertension and underwent three different therapeutic modalities, all with successful relief of symptoms. A review of the existing literature on past and current treatment options is done.

Hipotensión intracraneal espontánea. Una puesta al día

Introducción: La hipotensión intracraneal espontánea es un síndrome causado por la disminución del volumen de líquido cefalorraquídeo consecuencia de su fuga al espacio extradural. Aunque la ICHD-3 proporciona un alto nivel de especificidad diagnóstica, esta enfermedad puede manifestarse de forma atípica. Hasta en un 30% no es posible establecer el punto de escape, pero con el refinamiento de los exámenes de imágenes este porcentaje se ha reducido a un 15%-20%. Actualmente, su manejo no se encuentra estandarizado y las recomendaciones se basan en evidencia de limitada calidad metodológica, además de la variabilidad de protocolos entre distintos centros. Desarrollo En esta revisión actualizamos los procedimientos diagnósticos y terapéuticos. Por un lado, analizamos el rol de la resonancia nuclear magnética de encéfalo y médula espinal completa como primer paso diagnóstico y, por otro lado, señalamos los exámenes destinados a determinar la fuga de líquido cefalorraquídeo. Tal es el caso de la mielo-resonancia, la mielo-tomografía computarizada, tanto estándar, dinámica y por sustracción digital, además de la cisternografía con 111-Indium-DPTA. Sin embargo, determinar cuál de estos exámenes es el óptimo es objeto de debate. Lo mismo ocurre con el tratamiento: reposo; parche sanguíneo epidural a ciegas, parche guiado por fluoroscopia o tomografía computarizada, parche de fibrina; o cirugía. Conclusiones Se requiere de una mayor investigación, especialmente con trabajos multicéntricos controlados, para una mejor comprensión de la fisiopatología, el diagnóstico por imágenes, los enfoques terapéuticos y evaluación objetiva de los resultados clínicos. Solo así se establecerán pautas diagnósticas y de tratamiento validadas.

Introducction: Spontaneous intracranial hypotension is a syndrome caused by decreased CSF volume secondary to its leakage into the extradural space Although ICHD-3 provides a high level of diagnostic specificity, manifestations may be atypical, making diagnosis challenging. The site of leakage may be undetermined in point Up to 30% of cases, although with recent refinement of imaging, this percentage has been reduced to 15-20%. Currently, management is not standardized and recommendations are based on inconclusive evidence, with variability of protocols between centres. Development. In this review, we update diagnostic and therapeutic procedures. We analyse the role of whole brain and spinal cord MRI as a first investigation and review tests aimed at determining cerebrospinal fluid leakage, such as MRI myelography, conventional CT myelography, dynamic CT myelography, and digital subtraction CT myelography, as well as 111-Indium-DPTA cisternography. Determining optimal use of these investigations remains a matter of debate. The same is true for treatment: rest, blind epidural blood patch, fluoroscopy or CT-guided epidural blood patch, fibrin patch and surgery are discussed. Conclusión: Further research, especially multicentre controlled studies, is required to improve understanding of pathophysiology, diagnostic imaging, therapeutic approaches and to objectively assess clinical outcomes. Only then will diagnostic and treatment guidelines be evidence-based.

Síndrome de Balint y trombosis de senos venosos cerebrales: reporte de caso / Balint syndrome and cerebral venous sinus thrombosis: Case report

Introducción: El síndrome de Balint es un trastorno neurológico infrecuente, de etiología diversa, cuya presentación incluye la triada clásica de: simultagnosia, ataxia óptica y apraxia oculomotora, síntomas secundarios asociados a lesiones parieto-occipitales, con pronóstico variable según la etiología que se encuentre. A continuación, se reporta un caso secundario a una trombosis de senos venosos. Presentación del caso: Mujer de 66 años que ingresa a urgencias por cefalea aguda asociada a síntomas neurológicos progresivos con compromiso visual. Presentó tensión arterial elevada, simultagnosia, ataxia óptica y apraxia oculomotora. Los estudios imagenológicos reportaron hemorragia subaracnoidea por trombosis de seno sigmoideo izquierdo, por lo que se inició anticoagulación, antihipertensivo, con adecuada evolución del cuadro clínico. Discusión: A pesar de que el síndrome de Balint es un trastorno poco común, de etiología diversa, con escasos reportes a escala global, el caso comentado concordó con las características descritas en la literatura. El abordaje de la paciente en su atención inicial permitió la sospecha diagnóstica oportuna y la indicación de ayudas diagnósticas imagenológicas pertinentes. Tales ayudas soportaron un manejo temprano y la adecuada evolución y resolución del cuadro, en el contexto de la asociación del síndrome a una trombosis de senos venosos cerebrales (una etiología infrecuente). Conclusión: Mediante una historia clínica completa y minuciosa, junto a un adecuado examen neurológico, es posible hacer un acercamiento diagnóstico temprano que permita generar la sospecha del síndrome de Balint y la solicitud temprana de imágenes diagnósticas que orienten en el estudio de su etiología y manejo oportuno, con mejores desenlaces en el paciente.

Introduction: Balint Syndrome is a rare neurological disorder with multiple etiologies. The physical signs include a classic triad (simultagnosia, optic ataxia, and oculomotor apraxia). These symptoms are associated with parieto-occipital lesions, and the prognosis depends on the etiology. This article reports a case secondary to venous sinus thrombosis. Presentation of the case: A 66-year-old woman presented to the emergency room with acute headache associated with progressive neurological symptoms and visual impairment. She had high blood pressure, simultanagnosia, optic ataxia, and oculomotor apraxia. Imaging studies revealed subarachnoid hemorrhage due to thrombosis of the left sigmoid sinus, for which anticoagulation and antihypertensive therapy were started. The patient had a favorable clinical outcome. Discussion: Although Balint syndrome is a rare disorder of diverse etiology with few clinical cases reported globally, the case discussed here was consistent with the characteristics described in the literature. The patient's initial assessment allowed for timely diagnostic suspicion and appropriate imaging studies, which supported early management and the appropriate evolution and resolution of the condition, given the association of the syndrome with an uncommon cause as cerebral venous sinus thrombosis. Conclusion: A complete and thorough medical history, along with a proper neurological exam, can lead to an early diagnostic approach that raises suspicion of Balint's syndrome and prompts timely imaging studies to guide the investigation of its etiology and management, ultimately leading to better outcomes for the patient.
