The effect of allopurinol on cardiovascular outcomes in patients with type 2 diabetes: a systematic review.

Background: Cardiovascular disease (CVD) remains the main cause of death in patients with type 2 diabetes (T2D). Although hyperuricemia has been associated with multiple CV complications, it is not officially recognized as a target parameter for CVD risk reduction.

Aim: To systematically review the literature in order to determine whether treating hyperuricemia with allopurinol in patients with T2D reduces CVD risk.

Impaired left ventricular deformation and ventricular-arterial coupling in post-COVID-19: association with autonomic dysregulation.

Coronavirus disease-19 (COVID-19) has extended implications namely the long COVID-19 syndrome. We assessed over-time changes in left ventricular (LV) function, aortic stiffness, autonomic function, and ventricular-arterial coupling (VAC) in post-COVID-19 patients. We followed 34 post-COVID-19 subjects, up to 6 months post-hospital discharge.

The Role of Cell-derived Microparticles in Cardiovascular Diseases: Current Concepts.

Cardiovascular disease remains the main cause of human morbidity and mortality in developed countries. Microparticles (MPs) are small vesicles originating from the cell membrane as a result of various stimuli and particularly of biological processes that constitute the pathophysiology of atherosclerosis, such as endothelial damage. They form vesicles that can transfer various molecules and signals to remote target cells without direct cell-to-cell interaction.

Adherence and quality of life assessment in patients with asthma treatment with budesonide/formoterol via the Elpenhaler device: the COMPLETE study.

Background: Asthma is a chronic inflammatory disease of the airways that causes recurring episodes of wheezing, breathlessness, chest tightness and coughing. Inhaled drugs on a daily basis are the cornerstone of asthma treatment, therefore, patient adherence is very important.

Methods: We performed a multicenter, open, non-interventional, observational, prospective study of 716 adult patients diagnosed with asthma receiving FDC (Fixed-dose combination) budesonide/formoterol via the Elpenhaler device.

Expression of Tissue microRNAs in Ascending Aortic Aneurysms and Dissections.

Little is known about the role of serum and tissue mediators in the progression of ascending aortic aneurysms and dissections. We examined how the tissue expression of microRNAs and matrix metalloproteinases (MMPs), as well as the serum levels of osteoprotegerin, adiponectin, and high sensitivity C-reactive protein (hsCRP) are associated with these entities. We enrolled 21 patients with ascending aortic aneurysm, 11 with acute Stanford type A aortic dissection and 18 controls.

Differential Expression of microRNAs in Acute and Chronic Heart Failure.

Background: MicroRNAs modify protein expression at the post-transcriptional level, and their circulating levels may help identify the underlying molecular pathways.

Objective: The purpose of this study was to assess the differential expression of microRNAs related to myocardial cell energy substrate, autophagy, and ischaemia in chronic and acute heart failure (HF).

Methods: In this case-control study, we studied 19 patients with acute HF (AHF) and 19 patients with chronic HF (CHF).

Fungal Infections in Critically Ill COVID-19 Patients: Inevitabile Malum.

Patients with severe COVID-19 belong to a population at high risk of invasive fungal infections (IFIs), with a reported incidence of IFIs in critically ill COVID-19 patients ranging between 5% and 26.7%. Common factors in these patients, such as multiple organ failure, immunomodulating/immunocompromising treatments, the longer time on mechanical ventilation, renal replacement therapy or extracorporeal membrane oxygenation, make them vulnerable candidates for fungal infections.

Endothelial dysfunction in acute and long standing COVID-19: A prospective cohort study.

Background: Coronavirus disease-19 (COVID-19) is implicated by active endotheliitis, and cardiovascular morbidity. The long-COVID-19 syndrome implications in atherosclerosis have not been elucidated yet. We assessed the immediate, intermediate, and long-term effects of COVID-19 on endothelial function.

Weaning Failure in Critically Ill Patients Is Related to the Persistence of Sepsis Inflammation.

Introduction: Septic patients undergoing mechanical ventilation (MV) often experience difficulty in weaning. Th aim of this study was to determine whether inflammatory biomarkers of sepsis could be indicative of the failure or success of spontaneous breathing trial (SBT) in these patients.

Methods: Sixty-five patients on MV (42 septic and 23 intubated for other reasons) fulfilling the criteria for SBT were included in the study.

Thyroid disorders and cardiovascular manifestations: an update.

Cardiovascular disease (CVD) remains the leading cause of death worldwide, representing a major health, social, and economic issue. Thyroid disorders are very common and affect >10% of the adult population in total. The aim of this review is to describe the physiologic role of thyroid hormones on cardiovascular system, to present cardiovascular manifestations in patients with thyroid disorders, emphasizing in molecular mechanisms and biochemical pathways, and to summarize current knowledge of treatment options.

COVID-19 ARDS: Points to Be Considered in Mechanical Ventilation and Weaning.

The COVID-19 disease can cause hypoxemic respiratory failure due to ARDS, requiring invasive mechanical ventilation. Although early studies reported that COVID-19-associated ARDS has distinctive features from ARDS of other causes, recent observational studies have demonstrated that ARDS related to COVID-19 shares common clinical characteristics and respiratory system mechanics with ARDS of other origins. Therefore, mechanical ventilation in these patients should be based on strategies aiming to mitigate ventilator-induced lung injury.

The Role of Endothelial Related Circulating Biomarkers in COVID-19. A Systematic Review and Meta-analysis.

Background: Several studies have revealed the link between Coronavirus Disease 2019 (COVID-19) and endothelial dysfunction. To better understand the global pattern of this relationship, we conducted a meta-analysis on endothelial biomarkers related to COVID-19 severity.

Methods: We systematically searched the literature up to March 10, 2021, for studies investigating the association between COVID-19 severity and the following endothelial biomarkers: Intercellular Adhesion Molecule 1 (ICAM-1), Vascular Cell Adhesion Molecule 1 (VCAM-1), E-selectin, P-selectin, Von Willebrand Factor Antigen (VWFAg), soluble Thrombomodulin (sTM), Mid-regional pro-adrenomedullin (MR-proADM), and Angiopoietin-2 (Ang-2).

Dexamethasone in the Treatment of COVID-19: Primus Inter Pares?

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread globally, becoming a huge public health challenge. Even though the vast majority of patients are asymptomatic, some patients present with pneumonia, acute respiratory distress syndrome (ARDS), septic shock, and death. It has been shown in several studies that the severity and clinical outcomes are related to dysregulated antiviral immunity and enhanced and persistent systemic inflammation.

Pott disease: when lumbar pain is not innocent.

Tuberculosis is a mycobacterial infection that can affect the lungs as well as other organs. The involvement of the spine, although rare, can have major consequences if not diagnosed and treated in a timely and effective manner, such as residual deformities and neurological deficits. On occasion, the atypical presentation of tuberculous spondylitis may cause a delay in treatment and therefore lead to less favorable outcomes.

Study of inflammatory biomarkers in COPD and asthma exacerbations.

Introduction: Exacerbations are critical events in the course of asthma and chronic obstructive pulmonary disease (COPD). These events are potentially life-threatening, and the studies have shown that they have tremendous implications on long-term disease control and the overall prognosis of the patients. The aim of this study was to examine adipokines, cytokines and C-reactive protein (CRP) as potential biomarkers in asthma and COPD.

Lambda sign on a gallium scan: not always sarcoidosis.

Sarcoidosis is a systemic disease of unknown origin. We describe a case of sputum smear-and culture-negative tuberculosis that was diagnosed with histological examination of a surgical lung biopsy, as other entities such as sarcoidosis could not be excluded after extended investigation. Even a typical lambda sign on gallium scintigraphy proved to be misleading.

Smoking cessation in pregnancy: An update for maternity care practitioners.

Introduction: This paper provides an up-to-date summary of the effects of smoking in pregnancy as well as challenges and best practices for supporting smoking cessation in maternity care settings.

Methods: We conducted a qualitative review of published peer reviewed and grey literature.

Results: There is strong evidence of the effects of maternal tobacco use and secondhand smoke exposure on adverse pregnancy outcomes.

The lung microbiome dynamics between stability and exacerbation in chronic obstructive pulmonary disease (COPD): Current perspectives.

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disorder with a course that is not uniform for all COPD patients. Although smoking is considered as the major cause of the disease, persistent or recurrent infections seem to play a particular role in the disease establishment and progression. COPD is characterized by dysregulated immunity that has been associated with the bacterial colonization and infections.
