Reproducibility and concordance of 4 clinically developed programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) assays in triple-negative brea…

2020

Abstract Background Atezolizumab (an anti–PD-L1 antibody) has shown clinical activity alone or in combination with nab-paclitaxel in patients (pts) with first-line metastatic TNBC who have PD-L1 expression on their tumour-infiltrating immune cells (IC). We analysed the performance of 4 PD-L1 IHC assays for PD-L1 IC expression in TNBC. Methods Thirty archival TNBC tissue specimens were selected from a set of 107 based on PD-L1 IC expression per VENTANA SP142 ( 5%: 8 cases), to represent the distribution of PD-L1 IC–positivity in the pivotal atezolizumab studies (Emens et al., SABCS 2018; JAMA Oncol 2019). Serial histologic sections were stained with VENTANA SP142 and SP263, and DAKO 22C3 and…

Filamin C variants are associated with a distinctive clinical and immunohistochemical arrhythmogenic cardiomyopathy phenotype.

2020

Background: Pathogenic variants in the filamin C (FLNC) gene are associated with inherited cardiomyopathies including dilated cardiomyopathy with an arrhythmogenic phenotype. We evaluated FLNC variants in arrhythmogenic cardiomyopathy (ACM) and investigated the disease mechanism at a molecular level. Methods: 120 gene-elusive ACM patients who fulfilled diagnostic criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) were screened by whole exome sequencing. Fixed cardiac tissue from FLNC variant carriers who had died suddenly was investigated by histology and immunohistochemistry. Results: Novel or rare FLNC variants, four null and five variants of unknown significance, were id…

Non Invasive Imaging of Myocardial Infarction with Computed Tomography and Magnetic Resonance

2012

Myocardial infarction is a major cause of death and disability worldwide. Myocardial infarction may represent a major catastrophic event leading to severe hemodynamic failure or sudden death or it may occur repeatedly in patients with established heart disease. In this context, the role of imaging techniques may become useful for the understanding of the determinants in a preclinical setting before acute coronary events, and for an accurate and correct diagnosis of myocardial infarction. Three-dimensional noninvasive imaging techniques, such as Cardiac CT (CCT) and Cardiac MR imaging (CMR) were widely developed in the last two decades. These imaging techniques may provide new insights into …

Refractory Death Rattle: Deep Aspiration Facilitates the Effects of Antisecretory Agents

2011

Anticholinergic drugs, including atropine, hyoscine butylbromide, and scopolamine, have been shown to be equally effective in the treatment of death rattle. However, anticholinergic drugs may only be effective in reducing the production of further secretions, rather than eliminating the existing ones. A case is described in which a preventive procedure was undertaken to carefully eliminate secretions before starting anticholinergic drugs. Airway aspiration under light anesthesia removed secretions before starting anticholinergic drugs. Low doses of propofol were given intravenously to make a laryngoscopy feasible, allowing the complete aspiration of large amounts of tracheal secretions. No …

Survival prediction in patients undergoing ischemic cardiopathy

2009

The ischemic cardiopathy is the main cause of death in developed countries. New improved drugs and therapies have appeared last years. However, the interventionist strategy and the most powerful drugs may have complications, and hence, it is very important to know the risk of death associated with patients during their stay in the hospital, or in the next six months. Thus, it is possible to tune the best treatment for each individual patient. In this framework, the use of artificial neural networks is proposed with a double objective: survival prediction and the extraction of the parameters with best predictive capabilities. A cohort of 691 patients treated in the Hospital Clinic, in Barcel…

Preferences of Patients for Discussing Sudden Unexpected Death in Epilepsy

2017

Abstract People with epilepsy have increased mortality rates, which is partially attributed to sudden unexpected death in epilepsy syndrome (SUDEP). Poor seizure control appears to be the strongest SUDEP risk factor. Management of epilepsy and adherence to therapy is critical to seizure control. The belief by caregivers of negative influence caused by being informed about the syndrome is the main reason SUDEP is not disclosed. There are no clear recommendations when to disclose the risk of SUDEP and how much information should be provided. We addressed the preferences of Latvian epilepsy patients for discussing SUDEP as well as awareness of the syndrome. Our study involved 55 epilepsy patie…

Cardiac complications in thalassemia: noninvasive detection methods and new directions in the clinical management.

2004

The natural history of thalassemia has shown substantial change during these years. This applies for each aspect of the pathology (for example, endocrinological, hepatological and psychological) and also for the pathology that has presented and still presents the main cause of death: myocardial dysfunction. In this review, the pathophysiology of cardiac complications, possible role of myocarditis, new knowledge on pathogenesis, and noninvasive detection methods for iron overload in the heart are pointed out. Prophylaxis of cardiomyopathy and new therapy strategies of myocardial dysfunction, including the impact of the new chelation treatment, are discussed.

Cardiac magnetic resonance in the diagnosis of the unusually detected acute myocarditis in the young people: a case report

2021

Myocarditis is among the causes of arrhythmic sudden cardiac death (SCD) in young athletes, with viral infection being the most common cause worldwide. Myocarditis recently has been reported as one of the cardiac complications of coronavirus disease 2019 (COVID-19) in athletes. Here we present a case of a 20-year-old male recreational soccer player with an episode of loss of consciousness in the context of respiratory infection. The patient reports having woken up with symptoms of an upper respiratory tract infection, and after playing a soccer match, he developed dizziness and a headache. He then suffered vasovagal syncope without loss of sphincter control. Physical examination, heart ausc…
