Background and Objectives: Visceral artery aneurysms (VAAs) are rare but potentially catastrophic vascular abnormalities, particularly in pregnant patients or women of childbearing age. Rupture is often fatal for both mother and fetus, with mortality rates exceeding 70% in some series. While most VAAs are found incidentally, a subset may present acutely with nonspecific abdominal or flank pain, making early recognition and appropriate referral essential. This review article aims to provide General Practitioners (GPs) and emergency department (ED) clinicians with a practical approach to the recognition, investigation, initial management, and escalation pathways for VAAs. Results: Physiological and hormonal adaptations in pregnancy heighten aneurysm rupture risk. Despite this, imaging is frequently delayed. Computed tomography angiography (CTA) remains the gold standard for diagnosis and is safe in pregnancy when clinically justified, with fetal radiation exposure well below teratogenic thresholds. Guidelines from major vascular societies uniformly recommend repairing VAAs in pregnancy or women planning pregnancy irrespective of aneurysm size, and treating pseudoaneurysms urgently in all patients. Endovascular intervention is first-line where anatomy permits, while open or hybrid approaches remain essential in unstable presentations. The manuscript outlines practical steps for ED and GP settings, including haemodynamic stabilization, early obstetric involvement, transfer considerations for rural environments, reproductive counselling, and post-repair surveillance. Conclusions: With an increasing number of abdominal scans being performed in primary and tertiary settings, there is an associated increased volume of incidental findings that require work-up. This article outlines a practical investigation and management strategy for clinicians presented with VAAs, including in high-risk cohorts, emphasizing early imaging, inter-specialty coordination, and guideline-supported thresholds for intervention.

Background and Objectives: Shortages of dermatologists create significant barriers to care, particularly for inflammatory and history-dependent conditions where image-only artificial intelligence (AI) classifiers have limited applicability. Current teledermatology solutions largely focus on single-task, morphology-based neoplasm classifiers, leaving the vast majority of dermatologic presentations underserved. This study evaluated the diagnostic accuracy and management plan quality of Dermflow (Prava Medical, Delaware, USA), a proprietary dermatology-focused Multimodal Image-and-Data Assistant (MIDA) that autonomously gathers dermatology-specific history, integrates data with patient-submitted images, and outputs structured differential diagnoses and management summaries. Materials and Methods: Two AI systems, Dermflow and Claude Sonnet 4 (Claude, a leading vision–language model), analyzed 87 clinical images from the Skin Condition Image Network and Diverse Dermatology Images databases, representing 10 inflammatory dermatoses and 9 neoplastic conditions stratified across Fitzpatrick Skin Tone (FST) categories (I–II, III–IV, V–VI). For the diagnostic comparison, Dermflow received images and autonomously gathered clinical history, while Claude received identical images without history. For the management plan comparison, both systems received the correct diagnosis and the clinical histories gathered by Dermflow. The primary outcome was diagnostic accuracy. The secondary outcome was management plan quality, assessed by two blinded dermatologists across eight clinical dimensions using 5-point Likert scales. Chi-square tests compared diagnostic accuracy between models; t-tests and ANOVA compared management quality scores. Results: Dermflow achieved markedly superior diagnostic accuracy compared to Claude (86.2% vs. 24.1%, p < 0.001). Both models maintained consistent diagnostic performance across FST categories without significant within-model differences (Dermflow p = 0.924; Claude p = 0.828). Management plan quality showed no significant overall differences between models. However, composite management quality scores declined significantly for darker skin tones across both systems: Dermflow scored 4.20 (FST I–II), 3.99 (FST III–IV), and 3.47 (FST V–VI); Claude scored 4.35, 3.97, and 3.44, respectively (p < 0.001 for most pairwise FST comparisons within each model). Conclusions: Multimodal AI integrating targeted history with image analysis achieves substantially higher diagnostic accuracy than image-only approaches across both inflammatory and neoplastic dermatologic conditions. Autonomous history gathering addresses fundamental limitations of morphology-only classifiers and enables scalable, patient-facing triage across the full spectrum of dermatologic disease. However, both models demonstrated reduced management plan quality for darker skin tones despite receiving the correct diagnosis, suggesting persistent training data limitations that require targeted bias-mitigation strategies beyond domain-specific instruction.

Background and Objectives: Parkinson’s disease (PD) is a neurodegenerative disorder marked by bradykinesia, rigidity, and tremor. While deep brain stimulation (DBS) of the subthalamic nucleus (STN) and globus pallidus internus (GPi) effectively alleviates motor symptoms, the potential of targeting the substantia nigra pars reticulata (SNr) is less understood. This study investigates the effects of mid-term DBS of the SNr on motor function and neuroplasticity in a 6-hydroxydopamine (6-OHDA) rat model of PD. Methods: Adult male Sprague-Dawley rats (280–300 g) were divided into healthy control (n = 10), PD (n = 9), sham-DBS (n = 7), and SNr-DBS (n = 7) groups. Bilateral striatal 6-OHDA lesions induced PD. High-frequency (130 Hz, 60 µs) SNr-DBS was delivered for 14 days. Locomotor activity (open-field), gait (footprint method), and motor coordination (rotarod) were assessed. Tyrosine hydroxylase (TH) expression in the SN and c-Fos and BDNF expression in the cerebellum, prefrontal cortex (PFC), and ventrolateral thalamus were analyzed histologically. Results: SNr-DBS significantly improved ambulation and horizontal activity compared to the PD group (p < 0.05). Gait analysis showed significant improvements in forelimb/hindlimb stride length and stance width, while rotarod performance indicated enhanced motor coordination (p < 0.05). Histology revealed increased TH expression in the SN and elevated c-Fos and BDNF levels in the cerebellum, PFC, and thalamus in the SNr-DBS group vs. PD rats (p < 0.05). Conclusions: Mid-term SNr-DBS produced significant functional gains in motor activity and coordination in a 6-OHDA PD model, together with molecular evidence of dopaminergic enhancement and neuroplastic activation. These translational findings suggest that targeting the SNr may offer a clinically relevant alternative for patients with PD, particularly for those who may not optimally respond to conventional STN or GPi stimulation.

Background and Objectives: Visual evoked potentials (VEPs) are a simple, noninvasive method for detecting subclinical visual pathway involvement in multiple sclerosis. This study investigated the frequency of VEP abnormalities and their associations with baseline clinical, radiological, and cerebrospinal fluid (CSF) features in treatment-naïve patients with clinically isolated syndrome (CIS) or early relapsing-remitting multiple sclerosis (RRMS) without prior optic neuritis. Materials and Methods: We retrospectively reviewed newly diagnosed, treatment-naïve CIS/early RRMS patients evaluated between January 2022 and July 2024 who underwent CSF analysis. Pattern-reversal VEPs were recorded under standardized conditions. VEP abnormalities were analyzed as any or bilateral, and associations were assessed using group comparisons and multivariable logistic regression. Results: In 101 patients (mean age 31.8 ± 9.7 years; 72% female; median EDSS 1.0), latency prolongation occurred in 69 (42 any,27 bilateral) and amplitude reduction in 33 (22 any, 11 bilateral). Among patients with latency prolongation, both the number of OCB bands and the IgG index were higher (bilateral p = 0.032; any p = 0.007). In multivariable analysis, male sex (p = 0.032) and pyramidal/brainstem-onset presentation (p = 0.006) were independently associated with any amplitude reduction; neither was associated with latency abnormalities. Conclusions: VEP abnormalities are common early in the disease, even without a history of optic neuritis. Male sex and pyramidal/brainstem-onset presentation were associated with reduced amplitude, suggesting that amplitude decrease may reflect early tissue dysfunction and may be related to adverse baseline clinical features. Associations between intrathecal immune activation and prolonged latency may indicate subclinical demyelination of the visual pathways related to inflammatory activity. Larger longitudinal studies are needed to clarify the clinical significance of VEP abnormalities in early RRMS. Full article

Background and Objectives: Menopausal hormone therapy (MHT) is the most efficacious treatment for vasomotor symptoms and genitourinary conditions associated with menopause. Modern menopause care increasingly encompasses women with multimorbidity, renal or hepatic impairment, previous malignancies or thromboembolic disorders, advanced age, and polypharmacy—groups frequently underrepresented in randomized clinical trials. This evidence gap prompts significant inquiries about the relevance of trial-based recommendations to actual clinical practice. Materials and Methods: This narrative review offers a concentrated assessment of prominent worldwide clinical guidelines regarding menopausal hormone therapy through thematic synthesis. We examined position statements from the North American Menopause Society (NAMS), the European Menopause and Andropause Society (EMAS), NICE clinical guidelines, the ACOG Practice Bulletin on menopausal symptom management, the Endocrine Society clinical practice guideline, and pertinent UK guidance from RCOG, BMS, and BGCS. Data from systematic reviews, meta-analyses, and extensive observational studies were analyzed to contextualize guideline recommendations for populations often underrepresented in clinical trials, including women aged ≥65 years and individuals with multimorbidity or polypharmacy. Results: Only the NICE and EMAS recommendations expressly acknowledge clinical vulnerability or complexity (multimorbidity, frailty, and cancer survivorship) as foundational principles. NAMS and ACOG delineate risk categories but fail to offer a cohesive taxonomy of vulnerability. Polypharmacy and drug–drug interactions are inconsistently addressed across guidelines, and there is a deficiency of standardized prescribing algorithms. While routine safety monitoring is universally advocated, the intervals for follow-up and methods for risk categorization differ. Observational evidence consistently indicates route-dependent variations in cardiovascular and thromboembolic risk, with transdermal estrogen linked to a more advantageous safety profile in higher-risk individuals. Conclusions: Present menopausal therapy guidelines are methodologically sound; however, they insufficiently address the complexities of multimorbidity, polypharmacy, and organ dysfunction. A systematic conceptual framework that incorporates areas of clinical vulnerability may facilitate personalized benefit–risk evaluation in practical applications. Future guideline revisions should enhance clarity by incorporating polypharmacy concerns, monitoring strategies, and systematic risk stratification methods for clinically complicated patients.

Background and Objectives: Systemic mastocytosis (SM) is a clonal mast cell disorder characterized by abnormal mast cell accumulation and activation in multiple organs, leading to mediator-related symptoms, including anaphylaxis. Drug hypersensitivity reactions (DHRs) are a major clinical challenge in SM, but their frequency and characteristics remain undefined. This study aimed to evaluate the frequency of drug allergy, identify high-risk drug groups, investigate reaction characteristics, and examine the relationship between drug reactions, baseline serum tryptase levels, and SM subtypes in patients with SM. Materials and Methods: We retrospectively analyzed 34 patients diagnosed with SM between 2009 and 2024 at Ege University Faculty of Medicine. Clinical features, SM subtypes, baseline serum tryptase levels, and DHR characteristics were recorded. Reactions to antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol, anesthetics, radiocontrast media (RCM), and COVID-19 vaccines were graded using the Ring and Messmer anaphylaxis classification. Results: Among 34 patients, the mean age was 48.6 ± 13.3 years, 53% were male, and 10 (29.4%) had DHRs. The most common culprit drugs were NSAIDs (17.6%) and β-lactam antibiotics (14.7%). Anaphylaxis was the predominant reaction, frequently associated with hypotension. In 5 patients (14.7%), drug-induced anaphylaxis was the initial and only manifestation of SM. No hypersensitivity reactions occurred to quinolones, general anesthetics, or COVID-19 vaccines. Median baseline tryptase was 50.25 µg/L (min–max: 8.59–200.00) overall, and 41.85 µg/L (min–max: 19.00–200.00) among those with DHRs. Conclusions: Patients with SM are at increased risk of severe DHRs, particularly to NSAIDs and beta-lactam antibiotics. In some patients, drug allergy may be the first and only manifestation of SM. Measurement of baseline serum tryptase is essential in patients with drug-induced anaphylaxis. A comprehensive allergy assessment, including tolerance testing and individualized counseling, is crucial to ensure safe pharmacological management. Full article

Background and Objectives: Cardiovascular disease is the leading cause of mortality in patients with ANCA-associated vasculitis (AAV) after the first year post-diagnosis. This study investigated relationships between traditional risk factors, echocardiographic findings, disease activity, and major adverse cardiovascular events (MACE) in AAV patients. Aim: This retrospective single-center study aimed to evaluate the impact of traditional cardiovascular risk factors and echocardiographic parameters on the occurrence of MACE in patients with AAV. Materials and Methods: This study included adult patients with AAV who were evaluated between 2020 and 2025. Data collected included demographics, cardiovascular risk factors, Birmingham Vasculitis Activity Score version 3 (BVASv3), laboratory parameters, immunosuppressive therapy, and transthoracic echocardiography (TTE) findings. MACE was defined as myocardial infarction, stroke, revascularization, cardiovascular hospitalization, or cardiovascular death. Results: The cohort comprised 32 females (61.5%) and 20 males (38.5%), with a mean age of 62.4 ± 12.4 years. MACE occurred in 38.5% of patients. Male gender (p = 0.002), overweight (p = 0.016), hyperlipidemia (p = 0.003), and prior cardiovascular disease (p = 0.002) were significantly associated with MACE in univariate analyses. Patients with MACE had larger left atrial anteroposterior dimensions on the parasternal long-axis view (median 3.9 vs. 3.3 cm, p = 0.002) and lower left ventricular ejection fraction assessed by the modified biplane Simpson’s method (median 53% vs. 60%, p = 0.002). Valvular dysfunction was not associated with MACE in a statistically significant manner. Disease activity markers (BVASv3 and CRP) showed no significant correlation with cardiovascular events or echocardiographic parameters. Conclusions: Our results demonstrate that traditional cardiovascular risk factors are stronger determinants of MACE in AAV patients than disease-specific parameters. Cardiac structural changes, including left atrial dilation and decreased left ventricular ejection fraction, were significantly associated with cardiovascular outcomes. These findings underscore the importance of integrating systematic cardiovascular risk assessment and aggressive risk factor modification into standard AAV management protocols. Full article

Background and Objectives: After the publication by Haylen et al. introducing the MUSPACC (midline uterosacral plication anterior colporrhaphy combination) procedure, we implemented this technique in our clinical practice for the treatment of cystocele and vaginal vault prolapse (VVP). The aims of this study were to evaluate peri- and postoperative complications, as well as vaginal and urinary symptoms, including patient satisfaction 3 months postoperatively. Materials and Methods: A retrospective analysis was conducted on 58 women who underwent MUSPACC over a five-year period. Patient-reported outcomes were assessed using three prolapse-related items from the International Consultation on Incontinence–Vaginal Symptoms (ICIQ-VS) and the International Consultation on Incontinence Questionnaire–Urinary Incontinence Short Form (ICIQ-UI SF), administered preoperatively and at three months following surgery. Demographic characteristics, as well as perioperative and postoperative complications, were obtained through review of medical records. Results: At follow-up, patients demonstrated improvement in vaginal symptoms, with the mean preoperative ICIQ-VS score decreasing from 15.2 to 1.16. Among those with preoperative urinary incontinence (UI), 42.1% became completely dry after MUSPACC procedure alone. Three patients (15%) developed de novo UI. Perioperative complications occurred in one patient. The postoperative complication rate was 20.7% (12/58), including one patient who experienced a postoperative fistula between the right ureter and vagina. No further surgeries were required. Overall, 96.4% of patients were satisfied postoperatively. Conclusions: MUSPACC procedure appears to be an effective treatment for VVP and cystocele, with improvement in vaginal and urinary symptoms, high patient satisfaction, and a low rate of serious complications. Routine perioperative cystoscopy is now performed for immediate detection and management of urinary tract injuries. Full article

Objective: This review is to systematically evaluate the clinical effectiveness and safety of acupuncture therapy for patients with post-stroke neurogenic bladder (PSNB). Methods: We included randomized controlled trials (RCTs) evaluating any type of acupuncture treatment for PSNB. Data extraction and quality assessment using Cochrane Risk of Bias 2.0 were performed. Meta-analysis was conducted for total effective rate (TER) and urodynamic parameters. Results: Ten RCTs involving 727 participants were included. Meta-analysis showed that acupuncture was associated with a reduction in residual urine volume (RUV), and increases in maximum cystometric capacity (MCC), and maximal urinary flow rate (Qmax). Acupuncture also showed a higher TER compared to control groups (RR = 1.23, 95% CI [1.15, 1.33], p < 0.001). However, wide 95% prediction intervals for urodynamic parameters indicated substantial uncertainty for future clinical applications. Adverse events were mild and infrequent, but only partly reported in two studies among included trials. Conclusions: Acupuncture as an adjunctive therapy suggests potential trends for improving clinical efficacy and urodynamic parameters in PSNB patients. However, no definitive conclusions can be drawn regarding its clinical efficacy or safety due to the very low certainty of evidence, high methodological heterogeneity, and limited reporting of adverse events. Therefore, these results must be interpreted with extreme caution. Further high-quality, large-scale randomized controlled trials with standardized protocols are essential to establish robust evidence regarding its clinical effectiveness and safety.

Background and Objectives: Sleep-related breathing disorders (SRBDs) are common but often underdiagnosed in children. Early identification is essential, as untreated pediatric SRBDs can lead to cognitive, metabolic, and cardiovascular complications. This study aimed to estimate the prevalence of children at risk for SRBDs, defined as those screening positive based on Pediatric Sleep Questionnaire (PSQ) scores, and to analyze the association with potential risk factors in the general pediatric population of Lithuania. Materials and Methods: This cross-sectional study included 1929 children aged 2–17 years. Parents completed a questionnaire covering demographics, health status, and the PSQ. A validated Lithuanian version of the PSQ was used, with ≥8 (40%) positive responses indicating suspected SRBDs. Results: Overall, 14.9% of children were suspected of having SRBDs, with the highest prevalence among those aged 7–11 years (17.5%), followed by 2–6 years (14.9%) and ≥12 years (12.6%) (p = 0.032). In preschoolers (2–6 years), the strongest predictors were attention deficit hyperactivity disorder (ADHD; p < 0.001, OR 4.456, 95% CI 1.992–9.968) and allergic rhinitis (p < 0.001, OR 2.268, 95% CI 1.433–3.591). In children aged 7–11 years, endocrine diseases showed the strongest association (p < 0.001, OR 13.366, 95% CI 2.914–61.313), followed by ADHD (p = 0.001, OR 5.693, 95% CI 1.981–16.363) and adenotonsillar hypertrophy (p < 0.001, OR 3.079, 95% CI 1.839–5.156). In adolescents (≥12 years), SRBDs were primarily associated with ADHD (p < 0.001, OR 17.513, 95% CI 9.597–31.961) and endocrine diseases (p < 0.001, OR 6.214, 95% CI 2.965–13.020), while obesity remained significant (p < 0.001, OR 3.400, 95% CI 2.106–5.489). Conclusions: Approximately 15% of Lithuanian children were at risk for SRBDs. Risk factors differed by age: adenotonsillar hypertrophy in school-aged children, allergic rhinitis in preschoolers, and obesity in adolescents, whereas ADHD was associated across age groups.

Background and objectives: Acute colicky abdominal pain, involving visceral spasms and inflammatory mechanisms, is a common complaint in everyday medical practice. Despite its widespread use, clinical evidence on the fixed-dose combination of pargeverine 10 mg plus lysine clonixinate 125 mg remains limited. The objective of this study was to describe real-world clinical outcomes, safety, and patient-reported experience associated with this combination in routine practice. Materials and methods: This multicenter, observational, non-comparative, real-world study included adult patients with acute colicky abdominal pain of gastrointestinal, urological, or gynecological origin. Pain intensity was assessed using a visual analog scale (VAS) at baseline and at 5 ± 3 days. Secondary outcomes included time to pain relief, satisfaction with treatment, and safety. Associations between pain reduction and patient-reported outcomes were explored. Results: A total of 202 patients were analyzed. Significant pain reduction was observed across all etiologies (p < 0.001), with median VAS reductions ranging from 6 to 9 points (approximately 70% to 90% from baseline). More than 95% of patients reported early improvement, and sustained relief was maintained in more than 96% throughout the study period, regardless of the pain’s origin. Adverse events were infrequent (3%), mild in intensity (primarily transient gastrointestinal symptoms), and did not lead to treatment discontinuation. Conclusions: In real-world clinical practice, the fixed-dose combination of pargeverine and lysine clonixinate was associated with early and sustained, clinically meaningful pain reduction across multiple forms of acute visceral colicky pain, with a favorable safety and tolerability profile, supporting its relevance as a short-term therapeutic option in mild to severe acute pain.

Background and Objectives: Hereditary angioedema (HAE) represents a specific form of life-threatening inborn errors of immunity. Current guidelines recommend regular assessment of the disease burden, disease control and quality of life. This study describes the profile of HAE patients in Slovakia, disease control, quality of life, states of anxiety and depression, and socioeconomic situation. Materials and Methods: We used a set of standardized questionnaires—AE-QoL, AECT, HADS and Socioeconomic Status Questionnaire, and a non-standardized questionnaire—to describe the characteristics of the population. Results: We collected data on 56.44% (57 out of 101) of HAE adult patients registered in Slovakia. Moderate to severe HAE was present in 61.40% of patients; 73.68% were on long-term prophylactic treatment; and 19.30% received rescue treatment due to an acute HAE attack during the last 4 weeks. Most patients achieved lower AE-QoL scores, indicating a good quality of life. The AECT score indicated well-controlled disease in 91.23% of patients. Anxiety and/or depression scores were higher than normal in 17.54% of patients. Patients with HAE earned less than the average population, but most of them were economically active with relatively low rates of presenteeism and absenteeism. Only a minority of patients used social system benefits. Patients were exclusively cared for by relatives. Conclusions: The QoL scores achieved in all three standardized questionnaires indicate a good quality of life of HAE patients in Slovakia, which is associated with a high and specialized standard of care. Anxiety and/or depression were present in 17.54% of patients. Direct patients costs and social care costs are low, but there is an indirect socioeconomic burden on patients and their families.

Background and Objectives: Metacognition-related processes (e.g., confidence calibration, self-evaluation and the use of feedback) have been linked to cognitive insight, self-evaluation, and daily functioning in psychosis. However, clinic-based assessments only provide limited information. Digital methods may capture state-like variations and contextual factors, but it is unclear to what extent they operationalise core metacognitive monitoring constructs versus adjacent self-evaluative/insight-related constructs. We mapped digital approaches used to assess metacognition-related constructs across the psychosis spectrum, summarising the associated feasibility and validity. Materials and Methods: We conducted a scoping review (PRISMA-ScR) of psychosis-spectrum studies that used digital tools to assess metacognition-related targets. These included ecological momentary assessment/experience sampling (EMA/ESM), task-based paradigms with confidence ratings, and hybrid approaches. Searches covered MEDLINE (via PubMed), Scopus, and IEEE Xplore, with the final search run on 15 December 2025. We charted constructs, operationalisations, feasibility/engagement indices and reported links with clinical or functional measures. Results: The empirical evidence map comprised 13 studies directly assessing metacognition-related constructs; eight additional implementation/methodological sources were synthesised separately to contextualise feasibility, reporting, ethics, and governance. EMA studies more often assessed adjacent self-evaluative constructs, including context-linked self-appraisal bias, conviction, and self-report–context mismatch in daily life, whereas task-based studies more directly assessed confidence–accuracy calibration and feedback updating. Across EMA studies, greater momentary symptom severity and more restricted contexts were often associated with inflated self-evaluations and divergence from observer-rated functioning. Task-based studies indicated that confidence calibration and feedback utilisation may diverge from objective performance; in performance-controlled paradigms, some studies reported comparable metacognitive sensitivity/efficiency, but the overall evidence remains uncertain. Passive sensing was common in psychosis research but was rarely explicitly tied to metacognitive constructs. Conclusions: Current digital work spans both core metacognitive monitoring constructs and adjacent self-evaluative/insight-related constructs, rather than a single unitary construct. Clinical translation remains hypothesis-generating: interpretability may be improved by combining clinical anchors, low-burden EMA, and optional contextual streams, but thresholds, workflows, and signal-action rules require prospective validation.

Background and Objectives: Bladder cancer is one of the most common malignancies of the urinary tract and poses a significant clinical challenge due to its biological heterogeneity and high rates of recurrence and progression. Urothelial carcinoma represents the predominant histological subtype, ranging from non-muscle-invasive disease with relatively favorable outcomes to aggressive muscle-invasive and metastatic forms associated with poor prognosis. Accurate diagnosis, staging, prognostic stratification, and assessment of treatment response are therefore essential for optimal patient management. The objective of this review is to summarize and critically evaluate the current evidence on the role of positron emission tomography/computed tomography (PET/CT) in bladder cancer, with particular emphasis on [¹⁸F]FDG PET/CT and non-FDG radiotracers. Materials and Methods: A narrative review of the available literature was performed, focusing on clinical studies, review articles, and guideline documents addressing the use of PET/CT in bladder cancer. The literature search included articles published between 2000 and 2025, while earlier landmark studies were selectively included if considered historically important for understanding the development of PET/CT imaging in bladder cancer. The initial search yielded over 500 records; after screening titles and abstracts, more than 100 articles were selected for full-text evaluation. The analyzed evidence encompasses the clinical applications of [¹⁸F]FDG PET/CT and alternative radiotracers, including choline-, acetate-, methionine-, and sodium fluoride-based tracers, and fibroblast activation protein inhibitors (FAPI), across different stages of disease and clinical settings. Results: Conventional imaging modalities, such as computed tomography and magnetic resonance imaging, provide important anatomical information but remain limited in the evaluation of lymph node involvement, early metastatic disease, treatment response, and disease recurrence. Despite limitations related to physiological urinary excretion, [¹⁸F]FDG PET/CT has demonstrated clinical value in selected scenarios, particularly for staging, prognostic assessment, detection of recurrence, and response evaluation. To overcome FDG-related constraints, several non-FDG radiotracers have been investigated. Among these, FAPI PET/CT has emerged as a promising modality due to its ability to target the tumor stroma, potentially improving lesion detectability and tumor-to-background contrast. Conclusions: This review summarizes and critically evaluates current evidence on the role of PET/CT in bladder cancer, with a focus on [¹⁸F]FDG PET/CT and non-FDG radiotracers. The discussed studies highlight their applications in primary diagnosis, staging, prognostic assessment, detection of recurrence, and evaluation of treatment response, as well as their respective advantages and limitations. Furthermore, potential future directions for PET/CT imaging in clinical practice are outlined, emphasizing the need for further research to clarify the optimal use of established and emerging radiotracers.

Introduction: Lymph node status is a key prognostic factor of lung cancer. Although video-assisted thoracoscopic surgery (VATS) is widely used for early-stage disease, its consistency in achieving thorough lymph node dissection remains debated. While many studies show outcomes comparable to thoracotomy, others question its reliability for accurate staging in advanced cases. This study compared the oncologic efficacy of VATS and thoracotomy in pulmonary adenocarcinoma, focusing on lymph node dissection and postoperative outcomes. Materials and Methods: A retrospective analysis was conducted on 111 consecutive patients who underwent curative-intent resection for pulmonary adenocarcinoma between 2019 and 2023 at the “Prof. Dr. Alexandru Trestioreanu” Oncological Institute, 52 undergoing thoracotomy and 59 Video-Assisted Thoracoscopic Surgery (VATS). Results: Demographic and clinical characteristics were comparable between groups. Compared with thoracotomy, VATS was associated with a significantly higher number of harvested lymph nodes at stations 7 and 10. No significant differences between groups in the number of positive lymph nodes, postoperative morbidity, or 30-day mortality were observed. Conclusions: VATS appears to provide comparable lymph node retrieval and short-term outcomes to open surgery. These findings add valuable data from an underrepresented Eastern European population and support the broader adoption of minimally invasive techniques in lung cancer surgery. Full article

Background and Objectives: Cutaneous squamous cell carcinoma (cSCC) displays heterogeneous metastatic potential, and the role of sentinel lymph node biopsy (SLNB) in clinically node-negative patients remains debated. To evaluate tumor thickness and histological grade as predictors of sentinel lymph node (SLN) metastasis in high-risk cSCC and to assess the performance of a simplified pathology-based predictive model. Materials and Methods: This retrospective single-center study included consecutive patients with high-risk cSCC and clinically N0 status who underwent SLNB. Associations were examined using univariate and multivariable logistic regression, ROC analysis with bootstrap internal validation (2000 iterations), and decision curve analysis. Results: Thirty-four patients were analyzed; 12 (35.3%) had SLN metastases. SLN-positive patients had greater tumor thickness (median 5.5 mm vs. 3.0 mm, p = 0.006) and higher frequency of G2–G3 histological grade (91.7% vs. 45.5%, p = 0.011). Histological grade was the strongest independent predictor in multivariable analysis (OR 14.61, 95% CI 1.63–131.12). The combined model demonstrated apparently high discrimination in this small cohort (AUC 0.91; bootstrap 95% CI 0.79–0.99), though this estimate should be interpreted with caution given the limited number of events. A 4.0-mm threshold yielded sensitivity 83.3% and NPV 86.7%. Conclusions: In this exploratory single-center study, tumor thickness and histological grade were complementary predictors of SLN metastasis in cSCC. These findings are preliminary and require validation in larger prospective cohorts. Full article

Background and Objectives: Distal radius fractures (DRFs) are among the most common upper-extremity injuries in the elderly, with malunion leading to long-term pain and disability. This study aimed to compare the discriminative performance of the Cast Index (CI), Gap Index (GI), and Three-Point Index (TPI) for predicting malunion during follow-up after closed reduction and casting in elderly patients with dorsally displaced DRFs. Materials and Methods: This study retrospectively analyzed 274 patients aged ≥65 years (mean 73.6 ± 6.5 years) with dorsally displaced Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) 2R3A fractures treated conservatively between 2018 and 2023. Standard posteroanterior and lateral radiographs were evaluated immediately post-reduction, at 7–10 days, and at 4 weeks. Cast, Gap, and Three-Point Indices were measured independently by two observers, and the mean values were analyzed. Receiver operating characteristic (ROC) analysis was used to evaluate discriminative performance for the detection of malunion. Subgroup analyses were performed based on fracture stability according to La Fontaine criteria. Results: At the final follow-up, 136 fractures (49.6%) maintained acceptable alignment, while 138 fractures (50.4%) experienced malunion. There was no significant difference in radiographic parameters between groups immediately post-reduction or at 7–10 days. The Gap and Three-Point Indices were significantly higher in the malunion group at 7–10 days and at 4 weeks (p < 0.001), but the Cast Index showed no significant between-group difference. At 7–10 days, the Gap Index [Area Under the Curve (AUC) = 0.641; cut-off = 0.33] and the Three-Point Index (AUC = 0.640; cut-off = 1.51) demonstrated modest discriminative ability. In stable fractures, both indices were statistically significantly higher in the malunion group, whereas in unstable fractures, only the Three-Point Index was statistically significantly higher in the malunion group (p < 0.001). Conclusions: The Gap and Three-Point Indices showed greater discriminative ability than the Cast Index for malunion after conservative management of DRFs in elderly patients. Thresholds of GI ≥ 0.33 and TPI ≥ 1.51 at 7–10 days may serve as practical quantitative indicators to identify patients who may warrant closer follow-up and possible cast reassessment in conjunction with standard radiographic assessment and clinical judgment.

Background and Objectives: Patients with porcelain aorta (PA) pose major surgical challenges during aortic valve replacement, making transcatheter aortic valve replacement (TAVR) the preferred alternative. However, data on the prognostic significance of PA among TAVR recipients are limited. This study sought to evaluate whether PA is associated with adverse short-term outcomes following TAVR. Materials and Methods: Consecutive, surgery-naïve patients who underwent TAVR between 2012 and 2020 at a single institution were retrospectively analyzed. Based on preoperative CT scans, patients were categorized as having either porcelain aorta (PA) or non-calcific aorta (NC). Inverse probability of treatment weighting (IPTW) was used to minimize baseline differences, with standardized mean differences (SMD) < 0.1 indicating adequate covariate balance. Logistic regression addressed residual post-IPTW imbalances. Results: A total of 2037 patients with severe symptomatic aortic stenosis were identified, of whom 40 (2%) had PA. Compared to the NC population, PA patients were more likely to be younger (p = 0.002), had a higher prevalence of heart failure symptoms (p = 0.041) and peripheral artery disease (p = 0.006). After adjustment for preoperative characteristics, no significant differences were observed between groups in post-TAVR mortality (p = 0.498), stroke (p = 0.606), or postoperative creatinine levels (p = 0.827). However, PA patients experienced significantly longer in-hospital (p < 0.001) and ICU (p < 0.001) lengths of stay. Conclusions: In this single-center cohort, PA did not appear to confer additional risk of mortality, stroke or renal failure, although it remained associated with longer postoperative in-hospital and ICU lengths of stays. TAVR appears to be a safe and effective method of AVR when significant circumferential atherosclerotic aortic calcification precludes aortic cross-clamping. Full article

Background and Objectives: Postoperative pain after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) shows substantial interindividual variability, particularly during early mobilization. Although preoperative psychological vulnerability has been associated with less favorable pain trajectories in prior AIS research, evidence focused on the acute postoperative phase remains limited. This preliminary study evaluated whether preoperative psychological factors are associated with acute postoperative pain intensity, with separate assessment of resting and standing pain. Materials and Methods: A single-center retrospective cohort study included consecutive adolescents with AIS (<18 years) who underwent primary elective posterior instrumented spinal fusion between 1 January 2024 and 31 December 2025. Preoperative psychological variables were collected using validated instruments (STAIC-State, STAIC-Trait, Pain Catastrophizing Scale, HAQ/FDI, and inverted SRS-22). Pain intensity (VAS 0–10) was recorded at postoperative day (POD) 1, POD2, POD3, discharge, and 2-week follow-up in supine and standing positions. Derived endpoints included peak in-hospital standing pain, in-hospital standing pain burden (AUC), and standing–rest pain gaps. The prespecified inferential analysis used a linear mixed-effects model with fixed effects for time, position, preoperative STAIC-State, and position × STAIC-State interaction, with a patient-level random intercept. Results: Thirty-five patients were analyzed (mean age 15.2 ± 3.4 years; 62.9% female), with complete pain data at all timepoints. During hospitalization, standing pain was descriptively higher than resting pain (largest mean difference at POD2: 0.73 VAS points), with convergence at week 2 (both 1.52). In mixed-model analysis, pain significantly decreased at week 2 versus POD1 (β = −1.261, 95% CI −1.853 to −0.669; p < 0.001). Preoperative STAIC-State was not independently associated with postoperative pain (β = 0.030, 95% CI −0.065 to 0.124; p = 0.545), and no significant position × STAIC-State interaction was found (β = −0.008, 95% CI −0.079 to 0.064; p = 0.836). Conclusions: In this retrospective preliminary AIS cohort, postoperative pain improved significantly over time, while movement-evoked pain remained relevant during early recovery. In this preliminary cohort, no clear association was detected between preoperative state anxiety and acute postoperative pain intensity, supporting the need for broader multidimensional prognostic models in future prospective multicenter studies.
