Navigating Heart-Lung Interactions in Mechanical Ventilation: Pathophysiology, Diagnosis, and Advanced Management Strategies in Acute Respiratory Distress Syndrome and Beyond.

Patients in critical condition who require mechanical ventilation experience intricate interactions between their respiratory and cardiovascular systems. These complex interactions are crucial for clinicians to understand as they can significantly influence therapeutic decisions and patient outcomes. A deep understanding of heart-lung interactions is essential, particularly under the stress of mechanical ventilation, where the right ventricle plays a pivotal role and often becomes a primary concern.

Dulaglutide and Dapagliflozin Combination Concurrently Improves the Endothelial Glycocalyx and Vascular and Myocardial Function in Patients with T2DM and Albuminuria vs. DPP-4i.

In this study, we compared the effect of the combination of dulaglutide and dapagliflozin versus DPP-4 inhibitors on the endothelial glycocalyx, arterial stiffness, myocardial function, and albuminuria. : Overall, 60 patients were randomized to combined dulaglutide and dapagliflozin treatment (n = 30) or DPP-4 inhibitors (DPP-4i, n = 30) (ClinicalTrials.

Oxidative Stress Biomarkers in Hypertension.

Arterial hypertension is a silent and progressive disease with deleterious vascular implications on all target organs, including the heart, the brain, the kidneys, and the eyes. Oxidative stress, defined as the overproduction of Reactive Oxygen Species (ROS) over antioxidants, is capable of deteriorating not only the normal endothelial but also the cellular function with further cardiovascular implications. Xanthine oxidase activity, NADPH oxidase overexpression, and ROS production lead to hypertension and high arterial tone, culminating in end-organ damage.

Tailored Therapies for Cardiogenic Shock in Hypertrophic Cardiomyopathy: Navigating Emerging Strategies.

Hypertrophic cardiomyopathy (HCM) is a complex and heterogeneous cardiac disorder, often complicated by cardiogenic shock, a life-threatening condition marked by severe cardiac output failure. Managing cardiogenic shock in HCM patients presents unique challenges due to the distinct pathophysiology of the disease, which includes dynamic left ventricular outflow tract obstruction, diastolic dysfunction, and myocardial ischemia. This review discusses current and emerging therapeutic strategies tailored to address the complexities of HCM-associated cardiogenic shock and other diseases with similar pathophysiology that provoke left ventricular outflow tract obstruction.

Multifaceted Impact of SGLT2 Inhibitors in Heart Failure Patients: Exploring Diverse Mechanisms of Action.

Heart failure (HF) is a growing concern due to the aging population and increasing prevalence of comorbidities. Despite advances in treatment, HF remains a significant burden, necessitating novel therapeutic approaches. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) have emerged as a promising treatment option, demonstrating benefits across the entire spectrum of HF, regardless of left ventricular ejection fraction (LVEF).

Wearable Activity Trackers and Physical Activity Levels Among Members of the Athens Medical Association in Greece.

Introduction: Wearable Activity Trackers (WATs) offer real-time feedback on activity levels. We assessed the impact of WAT usage on physicians' exercise habits.

Methods: Physicians from the Athens Medical Association, Greece (n = 742) responded to a self-administered questionnaire evaluating usage of WAT, demographic characteristics, specialty, and physical exercise habits.

Influenza Vaccination Practices and Perceptions Among Young Athletes: A Cross-Sectional Study in Greece.

Background: Influenza vaccination among athletes is a crucial area in sports medicine. This descriptive, cross-sectional study aims to explore the vaccination practices and intentions regarding influenza vaccines among young athletes.

Methods: A structured, questionnaire-based study was conducted among students from the National School of Sports in Greece.

Significance of diabetes mellitus status in patients undergoing percutaneous left main coronary artery intervention.

Background: Diabetes mellitus (DM) is a modifiable risk factor for patients with coronary artery disease (CAD). Treatment with insulin correlates with advanced disease and has been associated with excess cardiovascular risk, but evidence on outcomes of patients with insulin-treated DM (ITDM) undergoing left main percutaneous coronary intervention (LMPCI) remains scarce.

Aims: The aim of the presented study is to evluate the risk attributable to DM and ITDM in patients undergoing LMPCI.

Markers of Vascular Dysfunction in Hypertension.

Hypertension is a modifiable cardiovascular risk factor and displays a rapidly growing incidence due to aging and the acquisition of an unhealthy lifestyle. Hypertension is linked to the development of target organ damage in several vascular beds such as coronary arteries, peripheral, cerebral, and renal arteries. Besides, along with the presence of other cardiovascular risk factors, it aggravates vascular dysfunction due to the aging process.

Endothelin-1 Plasma and Aqueous Humor Levels in Different Types of Glaucoma: A Systematic Review and Meta-Analysis.

: Several studies suggest the complex relationship between Endothelin-1 (ET-1) levels with various types of glaucoma. This systematic review and meta-analysis explore ET-1 levels in plasma and aqueous humor among different types of glaucoma. : A literature search (PubMed, ScienceDirect, Cochrane Library) was made up to April 2024 (PROSPERO: CRD42023430471).

Ticagrelor potentiates cardioprotection by remote ischemic preconditioning: the ticagrelor in remote ischemic preconditioning (TRIP) randomized clinical trial.

Objective: Remote ischemic preconditioning (RIPC) reduces periprocedural myocardial injury (PMI) after percutaneous coronary intervention (PCI) through various pathways, including an adenosine-triggered pathway. Ticagrelor inhibits adenosine uptake, thus may potentiate the effects of RIPC. This randomized trial tested the hypothesis that ticagrelor potentiates the effect of RIPC and reduces PMI, assessed by post-procedural troponin release.

Elevated VEGF-A Levels in the Aqueous Humor of Patients With Primary Open Angle Glaucoma.

Background/aim: The purpose of the current study was to compare the vascular endothelial growth factor-A (VEGF-A) levels in the aqueous humor of patients with primary open angle glaucoma (POAG) and non-glaucomatous eyes and reveal any potential statistically significant correlations.

Patients And Methods: This was an observational cross-sectional study. Aqueous humor samples (50-100 μl) were collected under aseptic conditions, from the anterior chamber at the start of glaucoma or cataract surgery.

Impairment in Right Ventricular-Pulmonary Arterial Coupling in Overweight and Obesity.

The association of obesity with right ventricular function and the interplay between right heart and pulmonary circulation is incompletely understood. We evaluate the role of obesity as a determinant of right ventricular-pulmonary artery coupling (RVAC). We retrospectively studied consecutive subjects without overt cardiovascular or pulmonary disease.

Our aim was to assess whether systemic endothelial dysfunction, evaluated non-invasively by flow mediated dilation (FMD), is associated with diabetic macular edema (DME) and to determine if it is further impaired in patients with diffuse-DME. Consecutive patients ( = 84) with type-2 diabetes mellitus (T2DM) and diabetic retinopathy were enrolled. DME was not present in 38 (non-DME) and present in 46 patients; 25 with focal and 21 with diffuse-DME.

Renal Congestion in Heart Failure: Insights in Novel Diagnostic Modalities.

Heart failure is increasingly prevalent and is estimated to increase its burden in the following years. A well-reported comorbidity of heart failure is renal dysfunction, where predominantly changes in the patient's volume status, tubular necrosis or other mechanical and neurohormonal mechanisms seem to drive this impairment. Currently, there are established biomarkers evaluating the patient's clinical status solely regarding the cardiovascular or renal system.
