Ventilator-associated pneumonia (VAP) is a common and serious nosocomial infection in mechanically ventilated patients and results in high mortality, prolonged intensive care unit- (ICU) and hospital-length of stay and increased costs. In order to reduce its incidence, it is imperative to better understand the involved mechanisms and to identify the source of infection. The role of the endotracheal tube (ET) in VAP pathogenesis became more prominent over the last decades, along with extensive research dedicated to medical device-related infections and biofilms. ET biofilm formation is an early and constant process in intubated patients. New data regarding its temporal dynamics, composition, germ identification and consequences enhance knowledge about VAP occurrence, microbiology, treatment response and recurrence.
This paper presents a structured analysis of the medical literature to date, in order to outline the role of ET biofilm in VAP pathogenesis and to review recommended methods to identify ET biofilm microorganisms and to prevent or decrease VAP incidence.

Incidental Finding of a Left Atrial Myxoma while Characterising an Autoimmune Disease
Although cardiac tumours are uncommon, cardiac myxomas account for more than fifty percent of all cases and are the most frequent primary cardiac tumour. They have a broad clinical spectrum, usually related to cardiac symptoms, peripheral embolic events or systemic manifestations. We present a case report of a 68-year-old man who presented with systemic symptoms and analytical features suggestive of an autoimmune disease. In the ensuing diagnostic procedures, a cardiac myxoma was found, and after surgical resection, both the systemic manifestations and the analytical abnormalities disappeared.
Resistance to Antimicrobians – A Global Problem with Sectoral Resolution
Mankind has been and still is constantly threatened by infectious diseases. Antimicrobials, used to treat infections, are considered one of the greatest discoveries of the 20th century because they saved millions of lives from diseases that had a high mortality rate. Mankind has been and is still constantly threatened by infectious diseases. Antimicrobials, used to treat infections, are considered one of the greatest discoveries of the 20th century because they saved millions of lives from diseases that had a high mortality rate. Current infectious pathology is worryingly extending due mainly to “globalization”, which confirms the current concept of “Infections Without Borders”. In this context, both the consumption of antimicrobial substances and, inherently, the resistance of the main pathogens involved have increased. Unfortunately, antimicrobials have become victims of their success because their abusive use in humans and animals has led to the emergence of resistance among clinically important pathogens. Each dose of antibiotic creates selective evolutionary pressures, resulting in pandemic spread of highly resistant bacterial clones. Resistance to antibiotics is one of the greatest threats to human health. A return to the pre-antibiotic era would not only make possible the development of epidemics caused by multidrug-resistant bacteria, a major threat to the population, but would also jeopardize some of the most valuable therapies in modern medicine, such as transplantation and immunosuppressive chemotherapy programmes –dependent on supportive antimicrobial treatments.

Perioperative Stress-Induced (Takotsubo) Cardiomyopathy in Liver Transplant Recipients
A comprehensive analysis of published cases of Takotsubo cardiomyopathy, occurred in liver transplant recipients in the perioperative period, has been attempted in this review. Predisposing factors, precipitating events, potential physiological mechanisms, acute and post-event management have been discussed.
Severe Fatal Systemic Embolism Due to Non-Bacterial Thrombotic Endocarditis as the Initial Manifestation of Gastric Adenocarcinoma: Case Report
Introduction: Nonbacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis, is a rare, underdiagnosed complication of cancer, in the context of a hypercoagulable state. NBTE represents a serious complication due to the high risk of embolisation from the sterile cardiac vegetations. If these are not properly diagnosed and treated, infarctions in multiple arterial territories may occur.
Case presentation: The case of a 47-year-old male is described. The patient was diagnosed with a gastric adenocarcinoma, in which the first clinical manifestation was NBTE. Subsequently, a hypercoagulability syndrome was associated with multi-organ infarctions, including stroke and eventually resulted in a fatal outcome.
Conclusions: NBTE must be considered in patients with multiple arterial infarcts with no cardiovascular risk factors, in the absence of an infectious syndrome and negative blood cultures. Cancer screening must be performed to detect the cause of the prothrombotic state.
