Antimicrobial therapy is a critical component of the successful management of orthopedic infections, but its effectiveness depends on patient-, surgery-, drug-, and hospital-related factors. The dramatic increase in the emergence of multidrug-resistant microbial strains necessitates new clinical approaches in order to prevent or limit this phenomenon and to ensure a favorable therapeutic outcome.

Biomarkers Involved in the Pathogenesis of Hemophilic Arthropathy.

Hemophilia, which is a rare disease, results from congenital deficiencies of coagulation factors VIII and IX, respectively, leading to spontaneous bleeding into joints, resulting in hemophilic arthropathy (HA). HA involves complex processes, including synovial proliferation, angiogenesis, and tissue remodeling. Despite ongoing research, factors contributing to HA progression, especially in adults with severe HA experiencing joint pain, remain unclear.

Debates Surrounding the Use of Antithrombotic Therapy in Hemophilic Patients with Cardiovascular Disease: Best Strategies to Minimize Severe Bleeding Risk.

Navigating through antithrombotic therapy in patients with both hemophilia and cardiovascular pathology presents a complex scenario with inherent challenges and opportunities. The presence of hemophilia, characterized by impaired blood clotting, adds a layer of complexity to the management of cardiovascular conditions requiring antiplatelet therapy and anticoagulation. Striking a delicate balance between the necessity for antithrombotic treatment to prevent cardiovascular events and the heightened risk of severe bleeding in individuals with hemophilia demands a nuanced and carefully considered approach.

Could Endothelin-1 Be a Promising Neurohormonal Biomarker in Acute Heart Failure?

Acute heart failure (AHF) is a life-threatening condition with high morbidity and mortality. Even though this pathology has been extensively researched, there are still challenges in establishing an accurate and early diagnosis, determining the long- and short-term prognosis and choosing a targeted therapeutic strategy. The use of reliable biomarkers to support clinical judgment has been shown to improve the management of AHF patients.

Role of arterial hypertension and angiotensin II in chronic kidney disease (Review).

Chronic kidney disease (CKD) is a major public health issue, due to its effect on the quality of life of patients and by the huge costs incurred in treating this disease. It is an irreversible process, characterized by the progressive loss of functional nephrons. CKD ultimately requires the support of renal function by dialysis or even renal transplantation.

ECG and Biomarker Profile in Patients with Acute Heart Failure: A Pilot Study.

Background: Biomarkers, electrocardiogram (ECG) and Holter ECG are basic, accessible and feasible cardiac investigations. The combination of their results may lead to a more complex predictive model that may improve the clinical approach in acute heart failure (AHF). The main objective was to investigate which ECG parameters are correlated with the usual cardiac biomarkers (prohormone N-terminal proBNP, high-sensitive cardiac troponin I) in patients with acute heart failure, in a population from Romania.

Cardiac Biomarkers in Sports Cardiology.

Sustained physical activity induces morphological and functional changes in the cardiovascular system. While mostly physiological, they can also become a trigger for major adverse cardiovascular events, the most severe of which are sudden cardiac arrest and sudden cardiac death. Therefore, any novel method which can help more accurately estimate the cardiovascular risk should be considered for further studying and future implementation in the standard protocols.
