Combined radiographic and ultrasonographic assessment of postoperative diaphragmatic dysfunction after cardiac surgery: incidence, predictors, and clinical outcomes — a prospective cohort study

Abstract Background Reported incidences of postoperative diaphragmatic dysfunction vary widely, largely because diagnostic criteria differ and preoperative imaging is seldom available; whether anatomical elevation, contractile impairment, or their combination carries clinical con...

Comparative study of subclinical synovitis and periarticular bone changes in psoriasis patients: impact of biological therapy

Abstract Background Psoriasis (PsO) is increasingly recognized as a systemic inflammatory disease associated with subclinical musculoskeletal involvement that may precede psoriatic arthritis (PsA). This study aimed to evaluate the prevalence of subclinical synovitis and periartic...

Metaheuristic-Based PI Controller Tuning Using a Multi-Error ITAE Objective Function for FOC-Controlled PMSM Drives in Electric Vehicle Applications

Permanent Magnet Synchronous Motors (PMSMs) are widely employed in electric vehicle (EV) propulsion systems because of their high efficiency, high power density, and superior dynamic performance. The performance of field-oriented control (FOC)-based PMSM drives strongly depends o...

Structural and Functional Cardiac Reverse Remodeling After Bariatric Surgery: A Prospective Comparison of Sleeve Gastrectomy and Roux-en-Y Gastric Bypass

OBJECTIVE: Obesity is associated with characteristic cardiac remodeling, including left ventricular (LV) hypertrophy, concentric geometry, and subclinical myocardial dysfunction. Bariatric surgery induces reverse cardiac remodeling; however, it remains unclear whether structural...
