Prognostic Value of Serial Alkaline Phosphatase-to-Albumin Ratio for Mortality After Transjugular Intrahepatic Portosystemic Shunt

Background: Prognostic assessment after transjugular intrahepatic portosystemic shunt (TIPS) remains challenging, and currently available scores are based mainly on pre-procedural variables. The alkaline phosphatase-to-albumin ratio (APAR) is a simple laboratory-derived marker th...

Longitudinal Radiographic Outcomes and Revision Burden After Magnetically Controlled Growing Rod Treatment for Early-Onset Scoliosis

Background: To evaluate longitudinal radiographic outcomes, exploratory radiographic response, and planned versus unplanned revision burden after magnetically controlled growing rod treatment in patients with early-onset scoliosis. Methods: We retrospectively reviewed 55 patients...

Breastfeeding and Supplementary Oral Feeding Methods in Very Preterm Infants: A Prospective Within-Infant Comparison

Background: Very preterm infants often require supplementary oral feeding while direct breastfeeding skills mature. We compared short-term feeding performance and suck-swallow-breath coordination (SSBC) across three oral feeding methods. Materials and Methods: In this prospective...

Pediatric community-acquired acute kidney injury at a quaternary-care emergency department: clinical outcomes and prognostic determinants

Community-acquired acute kidney injury (CA-AKI) in children is less well characterized than hospital-acquired AKI but may be associated with serious clinical outcomes. This study evaluated the clinical characteristics, etiologic distribution, short-term renal outcomes, and progno...

The Frontal QRS-T Angle and Cardiovascular Disease: A Narrative Review of Electrophysiological Basis, Measurement, and Clinical Utility

The QRS-T angle quantifies the divergence between the vectors of ventricular depolarization and repolarization and is regarded as a surrogate for global heterogeneity of ventricular repolarization. Its frontal-plane variant, calculated as the absolute difference between the autom...

Fabry Disease Screening in Kidney Transplant Recipients: A Single-Center Retrospective Study

Background: Fabry disease (FD) is an X linked lysosomal storage disorder caused by deficient α galactosidase A (α GAL A) activity, leading to progressive multisystem involvement, including kidney disease. Evidence on FD screening in kidney transplant recipients is limited. We aim...

Evaluation of Hemogram Parameters by Folate Status in Infants with Vitamin B12 Deficiency: A Potential Masking Effect

Background: Folate and vitamin B12 interact in one-carbon metabolism, and imbalance between them may influence hematological findings. Although high folate status may mask vitamin B12 deficiency in adults, evidence in infants is limited. This study evaluated the association betwe...

Safety of patient-facing AI-generated medical advice: a structured clinical evaluation using acute appendicitis scenarios

Abstract Background Patient-facing large language model–based chatbots are increasingly used to seek medical advice and support health-related decision-making. While these tools provide accessible health information, their safety in high-risk, time-sensitive clinical scenarios re...

The effect of pulmonary nodule presence on disease severity and course in ANCA-associated vasculitis: a multicenter cohort study

Pulmonary nodules are common in ANCA-associated vasculitis (AAV), but their clinical relevance remains unclear. This study assessed the influence of pulmonary nodules and radiological features on clinical characteristics and outcomes in AAV. In this multicenter retrospective coho...

Subclinical Cardiac Dysfunction in Children with Iron Deficiency Anemia Assessed by Tissue Doppler and Speckle-Tracking Echocardiography

OBJECTIVE: Iron deficiency is the leading cause of anemia in childhood and may induce cardiovascular adaptations, including increased heart rate, elevated cardiac output, plasma volume expansion, and myocardial remodeling. Beyond hematologic consequences, reduced iron availabilit...

Impact of smoking and antioxidant use on in vitro fertilization success rates: A retrospective cohort study

Objective: This study investigated the impact of smoking and antioxidant supplementation on in vitro fertilization (IVF) outcomes among couples undergoing IVF treatment at a tertiary infertility center. Methods: This retrospective cohort study included 327 couples who underwent I...

Mid-Term Outcome of Distal Ureteral Stump after (Hemi)Nephroureterectomy

Aims: The complete removal of the ureter minimises the risk of future morbidity associated with the distal ureteral stump (DUS), including febrile urinary tract infections (UTIs), lower quadrant pain and haematuria – the so-called ureteral stump syndrome (USS). This research eval...
