Challenges in Septic Shock: From New Hemodynamics to Blood Purification Therapies.

Sepsis and septic shock are associated with high mortality, with diagnosis and treatment remaining a challenge for clinicians. Their management classically encompasses hemodynamic resuscitation, antibiotic treatment, life support, and focus control; however, there are aspects that have changed. This narrative review highlights current and avant-garde methods of handling patients experiencing septic shock based on the experience of its authors and the best available evidence in a context of uncertainty.

Individualised, perioperative open-lung ventilation strategy during one-lung ventilation (iPROVE-OLV): a multicentre, randomised, controlled clinical trial.

Background: It is uncertain whether individualisation of the perioperative open-lung approach (OLA) to ventilation reduces postoperative pulmonary complications in patients undergoing lung resection. We compared a perioperative individualised OLA (iOLA) ventilation strategy with standard lung-protective ventilation in patients undergoing thoracic surgery with one-lung ventilation.

Methods: This multicentre, randomised controlled trial enrolled patients scheduled for open or video-assisted thoracic surgery using one-lung ventilation in 25 participating hospitals in Spain, Italy, Turkey, Egypt, and Ecuador.

In-hospital cardiac arrest: Incidence, prognostic factors and results.

Background And Aims: In-hospital cardiac arrest (CA) is a clinical entity with high morbidity and mortality that occurs in up to 2% of hospitalized patients. It is a public health problem with important economic, social, and medical repercussions, and as such its incidence needs to be reviewed and improved. The aim of this study was to determine the incidence of in-hospital CA, return of spontaneous circulation (ROSC), and survival rates at Hospital de la Princesa, and to define the clinical and demographic characteristics of patients with in-hospital CA.

Estimated metabolic equivalents of task do not correlate with the maximal oxygen consumption of patients undergoing lung resection surgery.

Background And Objective: Metabolic equivalent of task (MET) is a physiological measure that represents the metabolic cost of an activity of daily living. One MET is equivalent to the resting metabolic rate. METs can be estimated by questionnaires or calculated by measuring maximal oxygen uptake (VO2max).

Incidence, diagnosis, and outcome of immune-mediated thrombotic thrombocytopenic purpura: A nationwide survey by the Spanish registry of thrombotic thrombocytopenic purpura.

Background: Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare disease characterized by the presence of anti-ADAMTS13 autoantibodies. Achieving accurate information on incidence and customary disease management is important to provide appropriate diagnostic and therapeutic resources. The aim of this study was to determine the incidence and outcomes of iTTP in Spain.

Increased number of pulmonary megakaryocytes in COVID-19 patients with diffuse alveolar damage: an autopsy study with clinical correlation and review of the literature.

Pulmonary megakaryocytes participate in the pathogenesis of lung damage, particularly in acute lung injury. Although megakaryocytes are not mentioned as a characteristic histologic finding associated to pulmonary injury, a few studies reveal that their number is increased in diffuse alveolar damage (DAD). In this autopsy study, we have observed a relevant number of pulmonary megakaryocytes in COVID-19 patients dying with acute lung injury (7.

Lung pulse visualized through pleural effusion as a diagnostic sign of complete obstructive atelectasis of the left lung in a critical patient with respiratory failure.

Complete obstructive atelectasis occurs when mucous or a foreign body obstruct one of the main bronchi. Several lung ultrasound signs have been associated with this entity. We describe the case of a patient admitted to the surgical critical care unit in whom lung ultrasound led to a diagnosis of complete obstructive atelectasis, and the presence of pleural effusion provided direct visualization of lung pulse, a sign that has only previously been described by interpreting ultrasound artifacts.

Unraveling the Influence of Common von Willebrand factor variants on von Willebrand Disease Phenotype: An Exploratory Study on the Molecular and Clinical Profile of von Willebrand Disease in Spain Cohort.

The clinical diagnosis of von Willebrand disease (VWD), particularly type 1, can be complex because several genetic and environmental factors affect von Willebrand factor (VWF) plasma levels. An estimated 60% of the phenotypic variation is attributable to hereditary factors, with the ABO blood group locus being the most influential. However, recent studies provide strong evidence that nonsynonymous single nucleotide variants (SNVs) contribute to VWF and factor VIII phenotypic variability in healthy individuals.

Joint status in Spanish haemophilia B patients assessed using the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) score.

Aim: The use of musculoskeletal ultrasound (MSK-US) following protocols for haemophilic arthropathy and the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) score can help standardize monitoring in haemophilia. This study evaluated the joint status (elbows, knees and ankles) of patients with haemophilia B (HB) in Spain using MSK-US and the HEAD-US score.

Methods: Haemophilia B patients ≥14 years old were included in this observational, multicentre, cross-sectional study, regardless of their clinical condition, HB severity and treatment received.

Unraveling the effect of silent, intronic and missense mutations on splicing: contribution of next generation sequencing in the study of mRNA.

Large studies in von Willebrand disease patients, including Spanish and Portuguese registries, led to the identification of >250 different mutations. It is a challenge to determine the pathogenic effect of potential splice site mutations on mRNA. This study aimed to elucidate the true effects of 18 mutations on mRNA processing, investigate the contribution of next-generation sequencing to mRNA study in von Willebrand disease, and compare the findings with prediction.

Monitoring pulse pressure variation during lung resection surgery.

Background And Objective: Although pulse pressure variation (PPV) is an effective dynamic parameter widely used to predict the increase in cardiac output after the administration of fluids in abdominal surgery, its use in thoracic surgery is controversial. A study was designed to describe the behaviour of PPV during lung resection surgery.

Patients And Methods: A prospective observational study was conducted on adult patients scheduled for lung resection surgery.

Role of multimeric analysis of von Willebrand factor (VWF) in von Willebrand disease (VWD) diagnosis: Lessons from the PCM-EVW-ES Spanish project.

The multimeric analysis (MA) of plasma von Willebrand factor (VWF) evaluates structural integrity and helps in the diagnosis of von Willebrand disease (VWD). This assay is a matter of controversy, being considered by some investigators cumbersome and only slightly informative. The centralised study 'Molecular and Clinical Profile of von Willebrand Disease in Spain (PCM-EVW-ES)' has been carried out by including the phenotypic assessment and the genetic analysis by next generation sequencing (NGS) of the VWF gene (VWF).

Flavonoids and Platelet-Derived Thrombotic Disorders.

Thrombotic disorders are characterized by an increase in the probability of the formation of unnecessary thrombi that might be due to the activation of the coagulation cascade or the circulating platelets. Platelets or thrombocytes play an essential role in hemostasis but abnormal platelet function leads to the development of a number of cardiovascular complications, including thrombotic disorders. Under pathological conditions, platelets are associated with the development of different thrombotic disorders, including atherosclerosis, arterial thrombosis and stroke, deep venous thrombosis and pulmonary embolism; therefore, platelets are the target of a number of anti-thrombotic strategies.

Molecular and clinical profile of von Willebrand disease in Spain (PCM-EVW-ES): comprehensive genetic analysis by next-generation sequencing of 480 patients.

Molecular diagnosis of patients with von Willebrand disease is pending in most populations due to the complexity and high cost of conventional molecular analyses. The need for molecular and clinical characterization of von Willebrand disease in Spain prompted the creation of a multicenter project (PCM-EVW-ES) that resulted in the largest prospective cohort study of patients with all types of von Willebrand disease. Molecular analysis of relevant regions of the , including intronic and promoter regions, was achieved in the 556 individuals recruited the development of a simple, innovative, relatively low-cost protocol based on microfluidic technology and next-generation sequencing.

Molecular and clinical profile of von Willebrand disease in Spain (PCM-EVW-ES): Proposal for a new diagnostic paradigm.

The diagnosis of von Willebrand disease (VWD) remains difficult in a significant proportion of patients. A Spanish multicentre study investigated a cohort of 556 patients from 330 families who were analysed centrally. VWD was confirmed in 480.

Assessment of ALK status by FISH on 1000 Spanish non-small cell lung cancer patients.

Introduction: Patients with non-small cell lung cancer (NSCLC) harboring anaplastic lymphoma kinase (ALK) rearrangement selectively respond to ALK inhibitors. Thus, identification of ALK rearrangements has become a standard diagnostic test in advanced NSCLC patients. Our institution has been a referral center in Spain for ALK determination by Fluorescent in situ hybridization (FISH).

Long-term cicatrization analysis in periocular incisions for oculoplastic surgery performed with cold blade and Colorado needle.

Purpose: To compare the degree of satisfaction of patients and observers about scars secondary to skin incisions in oculoplastic surgery performed with cold blade versus Colorado microcautery needle.

Methods: A cross-sectional noninferiority comparative study was performed. Eighty patients undergoing surgery for blepharoptosis repair, lateral tarsal strip, or dacryocystorhinostomy with cold blade or Colorado needle between January 2011 and July 2011 were included.

The canonical transient receptor potential 6 (TRPC6) channel is sensitive to extracellular pH in mouse platelets.

The canonical transient receptor potential-6 (TRPC6) is a receptor-activated non-selective Ca(2+) channel regulated by a variety of modulators such as diacylglycerol, Ca(2+)/calmodulin or phosphorylation. The present study is aimed to investigate whether different situations, such as acidic pH, exposure to reactive oxygen species (ROS) or hypoxic-like conditions modulate TRPC6 channel function. Here we show normal aggregation and Ca(2+) mobilization stimulated by thrombin in TRPC6 KO platelets; however, OAG (1-oleoyl-2-acetyl-sn-glycerol)-evoked Ca(2+) entry was attenuated in the absence of TRPC6.

Mechanical endovascular procedure for the treatment of acute ischemic stroke caused by total detachment of a papillary fibroelastoma.

Papillary fibroelastomas (PFEs) are rare cardiac tumors. Despite their benign nature, they are associated with a high risk of embolic complications including stroke. Endovascular treatment has been reported as a safe procedure in patients with myxoma, the most common type of primary cardiac tumor.
