The aims of this paper were to asses the quality of life with the use of the SF36 Questionnaire in patients with chronic heart failure and to establish the relationship between specific biochemical variables and the various aspects of the quality of life. The scores for various components of the quality of life were significantly affected by hemoglobin levels, creatinine clearance, fibrinogen levels and gamma-glutamyl-transferase levels, while lipid fractions and liver enzymes did not proove to have a significant impact on the quality of life.

Hypertrophic cardiomyopathy (HCM) is the most common monogenic cardiac disease with a highly variable phenotypic expression, ranging from asymptomatic to drug refractory heart failure (HF) presentation. Pharmacological therapy is the first line of treatment, but options are currently limited to nonspecific medication like betablockers or calcium channel inhibitors, with frequent suboptimal results. While being the gold standard practice for the management of drug refractory HCM patients, septal reduction therapy (SRT) remains an invasive procedure with associated surgical risks and it requires the expertise of the operating centre, thus limiting its accessibility. It is therefore with high interest that researchers look for pharmacological alternatives that could provide higher rates of success. With new data gathering these past years as well as the development of a new drug class showing promising results, this review provides an up-to-date focused synthesis of existing medical treatment options and future directions for HCM pharmacological treatment.

What started with 41 hospitalized patients identified as having laboratory-confirmed coronavirus disease 2019 in Wuhan, China, by January 2, 2020, turned into an unprecedented pandemic with more than 113 million confirmed cases and a mortality exceeding 2.5 million deaths worldwide by the beginning of March 2021. Although the course of the disease is uneventful in most cases, there is a percentage of patients who become critically ill and need admission in the intensive care unit for severe respiratory failure. Numerous of these patients undergo invasive mechanical ventilation and have an extremely high mortality rate. For these patients, extracorporeal membrane oxygenation (ECMO) has emerged as a last standing resource. In the present study, the literature was reviewed to evaluate the worldwide data regarding the use of ECMO in the management of critically ill COVID-19 patients. ISI Thomson Web of Science was searched for articles with English language abstracts from inception to March 1, 2021, with 'ECMO in COVID-19' as key words. A total of 214 abstracts were screened (case reports, guidelines, reviews) and the most relevant articles were included in the present review. The use of ECMO in the management of critically ill patients with COVID-19-induced acute respiratory distress syndrome refractory to conventional mechanical invasive ventilation is increasing. By increasing the survival rate from less than 20% to more than 50%, ECMO proved to be a valuable resource in the management of the most challenging critically ill COVID-19 patients. Contents 1.

The gallbladder undergoes different types of pathologies, ranging from inflammatory to preneoplasia and finally to malignant lesions. Gallbladder carcinoma can be highly invasive, and it is known that chronic inflammation of the gallbladder can lead to preneoplastic abnormalities and subsequently malignant phenotypes. Gallbladder neoplasia has a low incidence but is associated with a very poor prognosis. An early diagnosis is therefore extremely important in order to improve the prognosis of patients. Immunohistochemical markers of the mucin family can distinguish between different types of gallbladder lesions. Mucins are glycoproteins that can be attached to threonine residues that are O -glycosylated (due to the hydroxyl group of this amino acid). Mucins are divided into two types: those that bind to the membrane, such as MUC1, and those that form gels or are secreted, such as MUC5AC. Various alterations in mucin expression have been revealed to be associated with the development of neoplasia, as they modulate cell growth, karyokinetic transformation, dedifferentiation, adhesion, invasion and immune surveillance. p53 is a tumor suppressor gene and is linked to the development of different types of neoplasia. The incidence of the p53 gene is variable in the pathophysiology of gallbladder cancer. Several studies have revealed an incidence of ~50% of the p53 gene in gallbladder tumors. Studying the immunohistochemical profile of mucins and the presence of different gene mutations in neoplastic lesions of the gallbladder and surrounding mucosa may contribute to the understanding of the pathophysiology of the disease and the mechanisms involved in tumor development, allowing the identification of patients at increased risk of developing neoplasia, thus leading to improved management.

Aortic aneurysms represent a very common pathology that can affect any segment of the aorta. These types of aneurysms can be localized on the thoracic segment or on the abdominal portion, with the latter being more frequent. Though there are similarities between thoracic and abdominal aortic aneurysms, these pathologies are distinct entities. In this article, we undertook a review regarding the different mechanisms that can lead to the development of aortic aneurysm, and we tried to identify the different manners of treatment. For a long time, aortic wall aneurysms may evolve in an asymptomatic manner, but this progressive dilatation of the aneurysm can lead to a potentially fatal complication consisting in aortic rupture. Because there are limited therapies that may delay or prevent the development of acute aortic syndromes, surgical management remains the most common manner of treatment. Even though, surgical management has improved much in the last years, thus becoming less invasive and sophisticated, the morbi-mortality linked to these therapies remains increased. The identification of the cellular and molecular networks triggering the formation of aneurysm would permit the discovery of modern therapeutic targets. Molecular and cellular mechanisms are gaining a bigger importance in the complex pathogenesis of aortic aneurysms. Future studies must be developed to compare the findings seen in human tissue and animal models of aortic aneurysm, so that clinically relevant conclusions about the aortic aneurysm formation and the pharmacological possibility of pathogenic pathways blockage can be drawn.
