Background/Objectives: Delirium is prevalent among intensive care unit (ICU) patients and is associated with prolonged ventilation, longer ICU stays, increased mortality, and post-discharge cognitive impairment. Because most current prediction tools were developed using European cohorts, their transportability to other ICU settings remains unclear. The device support burden has received limited a…

Background/Objective: Retinal fundus image quality directly affects ophthalmic interpretation and automated analysis. Existing multi-degradation methods provide adaptive restoration but offer limited spatial degradation encoding and frequency-level supervision for severely degraded images. This study aims to improve restoration fidelity while preserving retinal structures required by downstream c…

Background/Objectives: Cardiac surgery involves unique complexities that differ from those of general ICU populations. Traditional scoring systems often underperform due to the significant class imbalance between survival and mortality. This study utilized the MIMIC-IV database, integrating machine learning (ML) and feature engineering to develop an in-hospital mortality prediction model specific…

Background/Objectives: Frailty is increasingly recognized as a clinically relevant marker of reduced physiological reserve in surgical oncology. The modified 5-item frailty index (mFI-5) is simple and practical, but its clinical significance in oral squamous cell carcinoma (OSCC) remains incompletely defined. This study evaluated the association between mFI-5-defined frailty and postoperative com…

Background/Objectives: Postoperative hypothyroidism is a common complication following hemithyroidectomy and may necessitate lifelong levothyroxine replacement therapy. Although several clinical predictors have been identified, clinically applicable risk models integrating both clinical and ultrasonographic parameters remain limited. This study aimed to identify independent predictors of postoper…

Background/Objectives: Corneal power has the largest impact on the variability of intraocular lens (IOL) power predictions, and corneal data from different biometers cannot be used interchangeably. We quantified the systematic differences between the Zeiss IOLMaster 700 (IOLM) and the Heidelberg Engineering Anterion and derived strategies for using both devices interchangeably in IOL power calcul…

Background/Objectives: This study aimed to evaluate the relationship between CBCT-derived total pulp volume and chronological age in mandibular first molars (M1) and second molars (M2), and to explore the preliminary utility of volumetric pulp analysis as a supplementary indicator for age-related dental changes in a Turkish population sample. Methods: CBCT scans of 60 individuals (32 females, 28 …

Background/Objectives: Complete blood count inflammatory indices are widely studied in obstetrics but rarely compared directly. We compared five first-trimester indices, the systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), pan-immune-inflammation value (PIV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), for their associations …

Background/Objectives: UNet-based models dominate medical image segmentation. Transformers have been added as an internal variant to these UNet-based architectures to improve feature learning. However, they have limitations in generalization and computational efficiency. Motivated by this idea, we have designed a two-stage novel hybrid segmentation framework, where tuners are added in cascade to …

While traditionally focused on coronary anatomy, cardiac computed tomography now enables non-invasive myocardial tissue characterization. By evaluating late iodine enhancement (LIE) and extracellular volume (ECV), single-energy CT (SECT) provides a valuable alternative to cardiac magnetic resonance for assessing ischemic and non-ischemic pathologies. However, clinical implementation of SECT faces…

Incontinentia pigmenti (IP) is a rare, X-linked dominant genodermatosis caused by mutations in the IKBKG gene and characterized by sequential cutaneous stages following the lines of Blaschko. The highly inflammatory initial vesiculobullous stage frequently mimics severe neonatal infections, such as herpes simplex or bullous impetigo, leading to potentially dangerous diagnostic delays and unnecess…

Background/Objectives: Persistent atrial fibrillation (AF) is associated with complex structural, electrical, and functional myocardial remodeling that contributes to impaired cardiac performance, symptom burden, and adverse cardiovascular outcomes. Although restoration of sinus rhythm through electrical cardioversion remains a cornerstone of rhythm-control therapy, treatment success is tradition…

Background/Objectives: Febrile seizures (FS) are the most frequent seizure disorder in childhood. Growing evidence suggests that systemic inflammatory responses may contribute to FS pathogenesis. Easily accessible inflammatory markers derived from routine blood tests, including the neutrophil-to-lymphocyte ratio (NLR), prognostic nutritional index (PNI), and C-reactive protein-to-albumin ratio (C…

Background/Objectives: Low back pain (LBP) is associated with central alterations, but convergence across structural, functional, and network measures remains unclear. We characterized multimodal differences. Methods: Resting-state fMRI included 69 participants (37 patients, 32 controls); VBM retained 23 patients and 32 controls after structural-image quality control. Structural, local functional…

Paraneoplastic neurological syndromes are rare immune-mediated disorders that may represent the first clinical manifestation of an underlying tumor. This report describes a 58-year-old woman with rapidly progressive cerebellar dysfunction and anti-Yo antibodies in serum and cerebrospinal fluid. Definite PNS was diagnosed according to the PNS-Care Score criteria (score: 10/10). Oncological evaluat…

Distinguishing tuberculous spondylodiscitis (TS) from pyogenic spondylodiscitis (PS) on imaging remains clinically important because the two entities differ in antimicrobial strategy, surgical timing, and the urgency of microbiological workup, yet no single imaging sign is pathognomonic for either diagnosis. When tissue confirmation is delayed, imaging becomes the primary tool that shifts pre-tes…

Background/Objectives: Skin lesion classification remains challenging in real clinical settings because diagnostically relevant information is distributed across different imaging modalities, class imbalance is often severe, and overall performance alone may conceal important weaknesses in model behavior. In this study, a dual-view meta-aware model, termed DVM-SLC was developed for multi-class sk…

Background/Objectives: Chronic traumatic posterior lens dislocation may cause ocular hypertension through overlapping lens-induced and traumatic mechanisms. We report a delayed presentation with a dislocated hypermature lens, a phacolytic phenotype, an incomplete capsule, and severe pressure elevation persisting after lens removal. Case Presentation: A 47-year-old man presented 5 years after blun…

Background: The Six Sigma metric benchmarks analytical performance, but most reports assess one platform at one time point, merging trueness with imprecision. Using routine peer-group internal quality control (IQC), we profiled two clinical chemistry platforms over five months. Because peer-group IQC compares imprecision directly but positions trueness only against same-method peers, we character…

Choriocarcinoma is a highly malignant trophoblastic tumour characterised by the secretion of human chorionic gonadotropin (β-hCG). Depending on its origin, choriocarcinoma is divided into gestational (GCC) or nongestational (NGCC). The prognosis is poor due to its high malignancy and possible hemorrhagic metastasis to distant organs. In the present case, a 40-year-old woman presented to the ophth…
