Objective: The optimal surgical approach for 1.0–2.0 cm renal stones in solitary kidney patients remains controversial. This retrospective study compared mini-percutaneous nephrolithotomy (mPCNL) and flexible ureteroscopy (f-URS) outcomes in this vulnerable population. Methods: Between June 2018 and April 2024, 50 patients with solitary kidneys and 1.0–2.0 cm renal stones underwent either mPCNL (n = 26) or f-URS (n = 24). Outcomes included 3-month stone-free rate (SFR), complications (Clavien–Dindo classification), and renal function (serum creatinine, eGFR by CKD-EPI equation) at the baseline, 72 h, and 1 month. Results: Stone-free rates were comparable (mPCNL 96.2% vs. f-URS 91.7%, p = 0.157). The f-URS group demonstrated significantly less hemoglobin decline (2.2 ± 0.9 vs. 5.7 ± 2.4 g/dL, p < 0.001) and shorter hospitalization (4.1 ± 1.1 vs. 7.8 ± 1.6 days, p < 0.001). All Grade II complications (8.3%, requiring transfusion) occurred in the mPCNL group. At 1 month, serum creatinine decreased more with f-URS (15.4 ± 7.96 vs. 8.7 ± 4.23 μmol/L, p < 0.001), with greater eGFR improvement (16.7 ± 4.7 vs. 15.4 ± 5.2 mL/min/1.73 m², p = 0.023). Conclusions: In this retrospective cohort, f-URS achieved comparable stone clearance to mPCNL alongside a superior early safety profile and better short-term renal functional preservation. These preliminary findings suggest that f-URS represents a viable nephron-sparing option for this high-risk population. However, these results are considered hypothesis-generating, and further prospective, long-term studies are required to evaluate the durability of these functional benefits. Full article

Introduction & Objective: Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), with limited treatment options for steroid-resistant cases. Ruxolitinib, a JAK1/2 inhibitor, has shown promise in treating steroid-resistant acute (aGVHD), chronic (cGVHD), and overlap GVHD (oGVHD), but real-world data remain limited. This study evaluated the real-world efficacy and safety of ruxolitinib in allo-HSCT patients with steroid-resistant GVHD. Materials & Methods: This retrospective, multicenter study included adult patients treated with ruxolitinib for Grade II or higher aGVHD or moderate-to-severe cGVHD at nine centers in Turkey (2017–2024). Clinical characteristics, treatment responses, and adverse events were recorded. Primary outcomes were overall response rate (ORR) and overall survival (OS). Results: Among 80 patients (mean age: 39.3 ± 13.3 years; 60 males), 39 had aGVHD, 68 cGVHD, and 15 oGVHD. The ORR was 72 of 80 patients (90.0%) (complete response: 37 of 80 [46.3%], partial response: 35 of 80 [43.8%]). The 1-year and 2-year OS rates were 91.3% and 82.5%. Severe cGVHD (p < 0.001) and lack of response to ruxolitinib (p = 0.018) were associated with reduced OS. Adverse events included infections in 40 of 80 patients (50.0%), cytopenias in 23 of 80 (28.7%), and cytomegalovirus reactivation in 20 of 80 (25.0%). Conclusion: In this retrospective multicenter cohort, ruxolitinib was associated with high response rates in steroid-refractory GVHD, while disease severity remained a key determinant of survival, and findings should be interpreted as exploratory.

Background: Duloxetine, a serotonin–norepinephrine reuptake inhibitor, is widely used both preoperatively and postoperatively in patients with neuropathic low back pain. This study aimed to determine the impact of duloxetine administration on posterolateral spinal fusion in rats and to evaluate the dose-dependent relationship of this effect. Methods: A pre-established rat model for posterolateral spinal fusion was employed, and four equal groups were formed, each undergoing posterolateral spinal fusion surgery. Except for the control group, the other groups received duloxetine postoperatively starting on day 1 at doses of 30 mg/kg/day, 60 mg/kg/day, and 120 mg/kg/day for six weeks. All rats were sacrificed after six weeks. Fusion status was assessed using manual palpation, radiological examination with plain radiography, and histopathological evaluation. Results: No significant differences were observed between groups in manual palpation scoring or radiological scoring. Histopathological evaluations of new bone formation also showed no significant differences between groups. The number of inflammatory cells was found to be higher in the control group compared to the low- and moderate-dose duloxetine groups (p = 0.012). Neovascularization scores were slightly higher in the control group compared to the duloxetine-treated groups (p = 0.048). Conclusions: In this experimental rat model of posterolateral spinal fusion, duloxetine administration was associated with reduced inflammatory cell infiltration and mildly decreased neovascularization on histopathological evaluation. However, these histological differences did not translate into measurable differences in fusion outcomes, as assessed by manual palpation, radiological scoring, or new bone formation. Overall, postoperative duloxetine treatment did not demonstrate a detrimental effect on spinal fusion success, suggesting that its use for neuropathic pain management may be biologically applicable with respect to fusion healing in this animal model.

Background and Objectives: The role of tourniquet use in arthroscopic partial meniscectomy remains debatable. While traditionally adopted to enhance visualization and reduce intraoperative bleeding, concerns were raised regarding its impact on postoperative outcomes and potential adverse effects, such as muscle damage or delayed recovery. This systematic review aimed to evaluate whether the use of a tourniquet offers advantages in terms of surgical efficiency, patient recovery and complication rates in arthroscopic partial meniscectomy. Materials and Methods: A systematic review was conducted following PRISMA guidelines and registered in the PROSPERO database (CRD42025644740). A comprehensive literature search was performed in 5 databases including studies from the past 20 years. Only randomized controlled trials (RCTs) comparing tourniquet-assisted versus non-tourniquet procedures in adolescent and adult patients undergoing isolated arthroscopic partial meniscectomy matched our inclusion criteria and the analysis was performed on those. Methodological quality was assessed using the Cochrane RoB 2.0 tool. Data were synthesized either quantitatively or narratively, depending on the availability of statistical details. Results: Three RCTs with a total of 243 patients met the inclusion criteria. Operative time was shorter in tourniquet-assisted procedures in one study (p = 0.001), though comparable outcomes were achieved in non-tourniquet groups when pharmacological agents such as intra-articular adrenaline were used. No significant differences were observed between groups regarding postoperative pain (p = 0.22, p = 0.43), knee effusion (p = 0.96), range of motion (p = 0.91, p = 0.96), or time to return to functional activities (p = 0.9, p = 0.34, p = 0.23). Muscle damage, assessed by serum creatine phosphokinase CPK levels, did not differ between groups (p = 0.3, p = 0.093, p = 0.079). Intraoperative visibility and surgeon satisfaction rated higher in tourniquet groups (p = 0.002), although this was subjective and reported variably. No major tourniquet-related complications were recorded. Conclusions: The routine use of a tourniquet in arthroscopic partial meniscectomy provides limited intraoperative advantages and does not improve postoperative outcomes. Current evidence supports a selective rather than routine use of tourniquets, especially when pharmacological alternatives are available. Further high-quality studies are needed to define standardized protocols and assess long-term outcomes. Full article

Background/Objectives: This study aimed to evaluate macular choroidal blood flow dynamics and structural alterations in children with hyperopic anisometropic amblyopia and compare these findings with those of the fellow eyes. Methods: This retrospective observational study included 36 eyes from 18 children (mean age: 4.9 years) with unilateral hyperopic anisometropic amblyopia. Central choroidal thickness (CCT) was measured using enhanced depth imaging optical coherence tomography. Macular choroidal hemodynamics were assessed using laser speckle flowgraphy. Mean blur rate (MBR) was used as an index of blood flow, whereas beat strength (BS) was used as a measure of pulsatility. Ocular perfusion pressure (OPP) was also calculated. All parameters were compared between amblyopic and fellow eyes. Results: Amblyopic eyes demonstrated significantly greater CCT compared with fellow eyes (407.6 ± 84.9 µm vs. 326.4 ± 79.1 µm). Conversely, macular MBR was significantly lower in amblyopic eyes (9.28 ± 3.60 AU vs. 10.94 ± 4.68 AU), as was BS (5.73 ± 3.07 AU vs. 7.28 ± 3.59 AU). No significant differences were observed in central retinal thickness or OPP between amblyopic and fellow eyes. In amblyopic eyes, CCT was not significantly correlated with macular MBR or BS. Conclusions: Amblyopic eyes exhibited significant central choroidal thickening accompanied by reduced macular blood flow and pulsatility. These findings suggest that localized macular hemodynamic dysregulation may contribute to the pathophysiology of hyperopic anisometropic amblyopia. Full article

Background/Objectives: Cervical pain is defined as pain in the neck that may or may not radiate to one or both upper extremities and lasts at least one day. Headaches are within the spectrum of neck pain, defined as any painful sensation perceived in the head that can extend to the neck. They are classified as primary (migraines and tension headaches) or secondary (cervicogenic headaches) depending on their clinical presentation and associated symptoms. The objective of this review is to compare the effects of dry needling with and without spinal manipulative techniques versus the application of other physical therapy modalities. Methods: A systematic review was conducted searching articles compatible with the objectives of this study in PubMed, ScienceDirect, and Scopus databases using the search terms spinal manipulation, cervical manipulation, dry needling, headache, headaches, and migraine over the last five years and combined with the Boolean operators AND and OR. After screening, all studies underwent methodological quality assessments using the PEDro scale and qualitative synthesis for study design, patients’ characteristics, interventions, comparators, outcomes assessed and main results data. Results: Thirteen randomized clinical trials were selected. The quality of the studies is varied, with PEDro scale values ranging from six to eight. Dry needling and cervical manipulations have proven to be effective tools, compared to other interventions, in reducing pain and improving functionality in patients with headaches. Conclusions: Dry needling techniques and manipulations have shown significant effects on parameters related to pain, sensitivity, functionality, and general health in patients with headaches. However, future studies are necessary to more deeply analyze the long-term effects of both techniques. Full article

Inflammation and oxidative stress are key mechanisms in aging, contributing to neurodegenerative diseases, cardiovascular diseases, type 2 diabetes, obesity, and other conditions. In the aging process, the increase in reactive oxygen species and the decrease in antioxidant pathways damage cellular components, accelerating deterioration. Persistent inflammation and oxidative stress also favor the progression of diseases such as atherosclerosis, where LDL oxidation and infiltration in the arteries generate plaques that can lead to myocardial infarction or stroke. In addition, inflammation and oxidative stress can affect the immune system, as well as the development of chronic inflammatory diseases and nonalcoholic fatty liver disease, and may affect mental health, healthy menopause and muscle recovery. Research from both human studies and laboratory tests indicates that taking 80–320 mg per day of anthocyanin-rich extracts from bilberries and blackcurrants (Anthocyanin-EBB) can moderately enhance cholesterol levels, lower markers of inflammation, boost blood vessel health, increase insulin responsiveness, and reduce indicators linked to cardiovascular and metabolic risks. They also have antioxidant, anti-inflammatory and neuroprotective effects, helping in the prevention and management of chronic diseases. As a result, supplementation with anthocyanin-rich extracts may be a promising strategy to promote healthy aging and reduce the risk of development and progression of conditions related to oxidative stress and chronic inflammation. Nevertheless, due to the limited patient populations and short follow-up periods in most existing studies, long-term clinical trials are necessary to determine the definitive advantages of Anthocyanin-EBB in clinical practice.

Background/Objectives: The coexistence of chronic obstructive pulmonary disease (COPD) and type 2 diabetes mellitus (T2D) poses significant clinical challenges due to overlapping mechanisms of systemic inflammation, oxidative stress, hypoxia, and metabolic dysregulation. Patients with both conditions face higher risks of exacerbations, prolonged hospitalizations, cardiovascular events, and reduced quality of life. This review aims to summarize current evidence on the pathophysiological interplay between COPD and T2D and to evaluate the impact of lifestyle and pharmacologic interventions. Methods: A narrative review of the literature was conducted to evaluate the pathophysiological links between COPD and T2D, assess the effects of pharmacologic and lifestyle interventions, and highlight key gaps and priorities for future research, with an emphasis on integrated, evidence-based management for this high-risk population. Results: Lifestyle interventions, including smoking cessation and structured physical activity, remain foundational to management. Emerging evidence indicates that antidiabetic therapies, such as glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium–glucose cotransporter-2 inhibitors (SGLT-2is), may confer additional pulmonary, metabolic, and cardiovascular benefits. These agents modulate systemic inflammation, oxidative stress, endothelial function, and insulin sensitivity, potentially reducing COPD exacerbations, improving lung function, and enhancing survival. Safety concerns, including glucocorticoid-induced hyperglycaemia and hypoxia-related metabolic complications, underscore the need for careful monitoring and individualized therapy COPD patients. Conclusions: Optimal care requires a multidisciplinary, patient-centred approach integrating pulmonology, endocrinology, primary care, nutrition, and rehabilitation, alongside shared decision-making and patient education. Despite promising findings, critical knowledge gaps remain. Large, well-designed randomized controlled trials and standardized definitions are needed to guide personalized therapeutic strategies.

Background: In critically ill patients, tracheostomy decisions are driven by heterogeneous and dynamic clinical trajectories, and no universally accepted scoring system exists to reliably predict tracheostomy requirement. An accurate and interpretable prediction model could help earlier decision-making and potentially reduce prolonged mechanical ventilation (MV) and failed weaning. Methods: In this retrospective study, data from 6507 mechanically ventilated intensive care unit (ICU) patients were analyzed using an electronic clinical decision support system; 1049 patients required tracheostomy and 5458 did not. The primary outcome was the prediction of tracheostomy occurrence during ICU stay based on invasive mechanical ventilation (IMV) parameters obtained within the first five days. The secondary outcome was the identification of the most influential parameters guiding tracheostomy decision-making during early IMV. Ten machine learning algorithms were developed using an 80/20 train–test split. Model performance was assessed using discrimination, calibration, and clinical performance metrics. Explainability was evaluated using SHapley Additive exPlanations (SHAP) analysis. Results: Among all models, Gradient Boosting demonstrated strong discrimination and calibration performance (AUROC 0.92, AUPRC 0.56, specificity 97%, F1 score 0.46, Brier score 0.078). In the Gradient Boosting model, feature importance analysis demonstrated that secretion count was the strongest predictor of tracheostomy requirement, accounting for 14.72% of the model’s predictive contribution. This was followed by lactate level (6.12%), arterial pH (3.74%), and peak airway pressure (3.57%). SHAP-based analyses consistently identified secretion count as the strongest predictor of tracheostomy requirement, followed by lactate level, Glasgow Coma Scale (GCS), and arterial pH. In addition, SHAP provided clinically interpretable insights into the direction and magnitude of the effects of individual predictors. Conclusions: Machine learning models integrating early-phase ventilatory and physiological data may enable clinically meaningful prediction of tracheostomy requirement. The combination of strong performance and explainability suggests potential utility as a decision-support tool in critically ill patients requiring prolonged MV. Full article

Background/Objectives: This study aimed to evaluate the autoregulatory capacity of optic nerve head (ONH) tissue blood flow in response to intraocular pressure (IOP) fluctuations during vitrectomy in patients with proliferative diabetic retinopathy (PDR). We hypothesized that impaired autoregulation of ONH tissue blood flow in response to intraoperative IOP fluctuations could contribute to subsequent ONH atrophy and the development of visual field defects in PDR patients following vitrectomy. Methods: We included five eyes from five patients with PDR (mean age 70.6 ± 9.0 years) undergoing 25-gauge pars plana vitrectomy. ONH tissue blood flow was quantitatively assessed using intraoperative laser speckle flowgraphy. Mean blur rate in the tissue area (MT), an indicator of ONH tissue blood flow, was measured at baseline (infusion pressure 0 mmHg), during sustained elevation to 25 mmHg (at 5 and 10 min), and 1 min after return to baseline (11 min). IOP was modulated using the IOP Control system of the Constellation platform. Results: Elevation of IOP to 25 mmHg significantly reduced ONH tissue blood flow, with MT decreasing by 29% at 10 min compared with baseline (p < 0.05, Dunn’s multiple comparisons test). After IOP returned to baseline, MT significantly recovered compared with the 10 min measurement (p < 0.05) and returned to levels not significantly different from baseline (p > 0.05). Conclusions: MT decreases during intraoperative IOP elevation in PDR undergoing vitrectomy, but recovers after the return to baseline pressure, suggesting preserved short-term autoregulatory capacity. Careful IOP management during vitrectomy remains important in eyes with PDR. Full article

Background: Vascular injury after total knee arthroplasty (TKA) is rare but may be limb-threatening. Popliteal artery branch pseudoaneurysm is an uncommon complication that can present with nonspecific symptoms, potentially mimicking postoperative hematoma, infection, or deep venous thrombosis (DVT). Case presentation: A 79-year-old man underwent primary left TKA for advanced osteoarthritis (OA). Seven months later, he sustained a low-energy fall closed reduction and bracing were implemented. Due to recurrent episodes of instability with spontaneous self-reduction, a constrained revision TKA (R-TKA) was performed. Eighteen days after revision, the patient was readmitted because of persistent pain-related functional impairment. Duplex Doppler ultrasonography revealed a partially thrombosed pseudoaneurysm measuring 33 × 37 mm arising from a popliteal/genicular branch. Computed tomography angiography (CTA) confirmed a partially thrombosed pseudoaneurysm with a contrast-filled component within a larger periarticular fluid collection. This suggested a second, smaller pseudoaneurysm along the feeding vessel; hemarthrosis and soft-tissue edema were also present. After multidisciplinary evaluation, selective catheter angiography via left common femoral access was performed, and the injured branch was occluded using coil embolization combined with n-butyl cyanoacrylate tissue adhesive. Completion angiography demonstrated successful exclusion of the pseudoaneurysm without complications. Conclusions: Delayed pseudoaneurysm of a popliteal artery branch should be considered after revision TKA in patients with atypical swelling, hemarthrosis, or disproportionate pain. Duplex ultrasound and CTA are complementary diagnostic tools, and endovascular embolization provides a minimally invasive, effective, and low-morbidity treatment option when the lesion involves a branch vessel.

Background/Objectives: Nonunion after tibiotalocalcaneal (TTC) arthrodesis remains challenging, especially in revision settings where union rates are substantially lower than in primary procedures. Biological adjuncts are commonly used to enhance healing, yet most described methods employ fibular onlay struts and cancellous autograft. To our knowledge, intramedullary placement of a fibular autograft for ankle fusion has not previously been reported. This study presents a revision of TTC arthrodesis nonunion treated with this technique and summarizes existing evidence on revision ankle arthrodesis, fibular grafting, and bone marrow aspirate concentrate (BMAC). Methods: We report a revision TTC arthrodesis nonunion managed with a decorticated intramedullary fibular autograft spanning the tibiotalar canal, supplemented with cancellous iliac crest autograft and BMAC. A review of PubMed, Scopus, and Google Scholar (search date: 1 September 2025) was performed to identify studies addressing revision ankle fusion, fibular grafting techniques, and BMAC use in foot and ankle arthrodesis. Primary outcomes included union and complications, with CT-based assessment prioritized when available. Results: At 3 months, radiographs and CT demonstrated progressive osseous bridging consistent with fusion; the patient achieved pain-free weight-bearing without complications. Conclusions: Intramedullary fibular autograft in revision TTC arthrodesis is a novel biological-mechanical strategy that leverages endosteal contact and axial stability while augmenting osteogenesis with cancellous autograft and BMAC. The review supports the biological plausibility and safety of this approach and underscores the importance of CT-based assessment. Full article

Background/Objectives: To analyze possible epigenetic changes (miRNA) in systemic lupus erythematosus (SLE) patients on a Mediterranean diet (MD) supplemented with extra virgin olive oil (EVOO). Methods: Fifteen SLE patients with medium/high MD adherence were randomized into an intervention group (IG) (daily supplementation of 40 mL of EVOO for 24 weeks) or to a control group (CG). miRNA profiles from blood peripheral cells were analyzed pre-/post-intervention using next-generation sequencing. Differential expression analysis was performed by DESeq2 in R to determine changes in the log2FC. Functional enrichment analysis was performed using GeneCodis 4. Results: EVOO supplementation resulted in changes in the expression of 16 miRNAs in the IG. Compared to the CG, two miRNAs showed upregulation (miR-451a, miR-1307-5p) while five showed downregulation (miR-193b-50, miR-134-5p, miR1287-5p, miR-124-3p, miR-654-3p). miR-124-3p, which has been proposed to be an SLE biomarker, showed the lowest relative expression after EVOO supplementation (L2FC −3.36; p_unadj = 0.025), whereas miR-1307-5p (L2FC 1.115 p_unadj = 0.02) and miR-451a (L2FC 0.77 p_unadj = 0.036) showed the highest relative abundance. The functional enrichment analysis showed that Th1 and Th2 cell differentiation and the complement/coagulation cascades were among the top ten most significantly enriched pathways. Conclusions: Our data suggest that MD supplementation with EVOO leads to changes in the profile of miRNAs in SLE patients, potentially impacting disease pathogenesis. Further research is needed to validate these preliminary findings and the mechanisms by which EVOO modifies miRNA expression in the context of this disease. Full article

Parkinson’s disease (PD) is the fastest-growing neurodegenerative disease affecting 90 thousand new Americans each year. PD includes motor and non-motor symptoms, resulting in progressive disability and difficulty in completing activities of daily living. Freezing of Gait (FoG) is one of the common disabling symptoms of PD, characterized by difficulties in initiating walking, resulting in gait abnormalities and increased risk of falling (RoF) and fear of falling (FoF). Clinical management of FoG is difficult as it is minimally responsive to both pharmacological and surgical interventions. In fact, these interventions can paradoxically worsen of FoG. Additionally, PD patients with FoG have reported worse health-related quality of life (HR-QoL) due to limitations in mobility, activities of daily living (ADL), bodily discomfort, stigma, and social isolation. Despite its increasing treatment and management of FoG is difficult due to its paroxysmal and heterogeneous nature. Therefore, there is a growing need for effective, evidence-based management and intervention approaches for FoG. Some current techniques used to manage FoG are physical therapy, exercise, gait training, and balance training; however, due to a lack of patient adherence, accessibility concerns, and the need for continuous supervision and individualized feedback, the long-term effectiveness of these interventions remains limited and challenging to achieve in real-world settings. A new promising avenue for managing PD is the use of wearable technology, which can provide audiovisual, via augmented and virtual reality (AR/VR), and tactical cueing to offset FoG, thereby enhancing independence in PD patients. In this comprehensive review, we will provide an overview of the symptoms, monitoring, and treatment of PD, with a focus on the neuroanatomy and treatment of FoG. We will review and critique the extant literature on the use of AR/VR technology in the management of FoG. Finally, the challenges and risks associated with wearable technology in FoG management will also be identified. Full article

Background: Continuity of care for rheumatoid arthritis patients within regional networks enables stable long-term clinical data collection, despite chronic rheumatologist shortages in Japan. We determined 5-year drug survival and discontinuation reasons for eight biological disease-modifying antirheumatic drugs (bDMARDs) using a regional multicenter registry. Methods: We retrospectively analyzed 1182 patients initiating their first (naïve, n = 784) or subsequent (switch, n = 398) bDMARD between May 2001 and August 2022 across five institutions. The primary endpoint (5-year drug survival) and secondary endpoints (discontinuation risk factors and cumulative incidence of reasons) were evaluated using Kaplan–Meier curves, Cox proportional hazards, and Fine & Gray models. Results: Baseline characteristics varied significantly among bDMARDs. Five-year drug survival in the naïve cohort ranged from tocilizumab (50.8%) to golimumab (22.6%); in the switch cohort, from abatacept (42.6%) to infliximab (10.0%). In multivariable Cox analysis of naïve patients, male sex (hazard ratio [HR] = 1.49, 95% confidence interval [CI] = 1.09–2.02), lower baseline 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR) (HR = 0.90, 95% CI = 0.82–0.99), and absence of methotrexate co-therapy (HR = 0.73, 95% CI = 0.55–0.97) predicted discontinuation. The lower baseline DAS28-ESR association potentially reflects successful courses toward intentional cessation following remission. Discontinuations were attributed to inadequate response (27.1%), non-adverse events (25.3%), and adverse events (17.3%). Conclusions: Tocilizumab and abatacept demonstrated the highest retention rates in biologic-naïve and switch cohorts, respectively. Early, individualized drug selection and dose optimization are crucial to maximizing long-term bDMARD effectiveness before switching. Full article

Background: Laryngospasm is defined as glottis closure due to reflex constriction of the laryngeal muscles. It is one of the most common complications following pediatric anesthesia that can lead to hypoxemia, bradycardia, or aspiration. Laryngospasm following tracheal extubation has different reasons: presence of secretions, foreign body in the airway, or pain at the site of surgery. Propofol is usually used as an induction or maintenance agent. However, its use with the subhypnotic dose (0.5 mg/kg) is increasing nowadays for reducing the incidence of laryngospasm. This systematic review and meta-analysis aim to assess the efficacy of subhypnotic propofol in reducing the incidence of laryngospasm and respiratory complications in children following tonsillectomy or adenotonsillectomy and before extubation. Methods: We systematically searched the following databases: PubMed, Cochrane Library, Scopus, and Web of Science. Studies were included if they used propofol with a low dose (0.5 mg/kg) following tonsillectomy and before extubation. Both Randomized Controlled Trials (RCTs) and cohort studies published up until 27 December 2025 were included. We used the R software for statistical analysis. We employed a random-effects model for the analysis. Continuous outcomes were analyzed as mean differences (MD) and dichotomous data as risk ratios (RR), with 95% confidence intervals (CI). Heterogeneity was assessed using I² statistics. Results: Our review included four RCTs and one prospective cohort study with 593 participants. Our analysis showed that propofol was significantly associated with a low incidence of laryngospasm (RR = 0.25, 95% CI 0.13–0.49), cough (RR = 0.08, 95% CI 0.01–0.62), and agitation (RR = 0.15, 95% CI 0.03–0.72) compared with the control group. However, there were no significant differences regarding laryngeal occlusion (RR = 0.70, 95% CI 0.20–2.46), cyanosis (RR = 1.13, 95% CI 0.14–9.43), stridor (RR = 1.38, 95% CI 0.76–2.50), and the duration of surgery (MD = 1.81, 95% CI −0.74 to 4.36). Conclusions: Our findings state that propofol had a lower significant incidence of laryngospasm than the control. Trial sequential analysis for laryngospasm indicated that evidence is conclusive. However, regarding the other outcomes, the evidence is still inconclusive, which suggests the need for future large-scale RCTs with larger sample sizes to validate these findings. Full article

Objective: To develop and validate a multidimensional nomogram for predicting 28-day all-cause mortality in patients with post-traumatic acute respiratory distress syndrome (ARDS). Methods: A retrospective analysis was conducted on 667 post-traumatic ARDS patients from the MIMIC-IV database, divided into training (n = 466) and validation (n = 201) cohorts (7:3). LASSO regression combined with the Boruta algorithm was used to screen variables and construct a nomogram. Model performance was evaluated by AUROC, calibration curves, and decision curve analysis (DCA) with SHAP analysis to identify core predictors. Results: Ten variables (e.g., lactate, platelet transfusion units, D-dimer) were selected and used to construct the nomogram model. The nomogram showed superior discriminative ability (AUROC = 0.848 in training set, 0.846 in validation set) compared with SOFA, APACHE II scores, and machine learning models (XGBoost, random forest). Calibration curves confirmed good agreement between predicted and actual risks, and DCA indicated better clinical net benefit. SHAP analysis identified lactate and platelet transfusion units as core risk factors and albumin and base excess trauma as protective factors. Conclusions: The nomogram has excellent predictive efficacy and interpretability, providing a reliable tool for clinical intervention in post-traumatic ARDS patients. Full article

Introduction: Balancing hypnosis and antinociception during general anesthesia remains challenging, as traditional clinical and hemodynamic signs incompletely reflect cortical and nociceptive processing. Electroencephalogram (EEG)-derived indices such as qCON (hypnosis) and qNOX (nociception probability) (Quantium Medical, Barcelona, Spain), as well as their predecessors IoC1 (Index of consciousness) and IoC2 (Angel-6000 A multi-parameter Anesthesia Monitor, Shenzen Weihao Kang Medical Technology Co., Ltd., Shenzen, Guangdong, China), have been developed to provide a dual assessment of anesthetic state. Their clinical role, technical limitations, and impact on drug titration, however, remain incompletely defined. Methods: A structured narrative review was conducted based on studies investigating IoC/qCON and qNOX in the context of anesthetic depth or nociception monitoring. Studies were grouped into three thematic domains: (1) validation against clinical or EEG standards, (2) use in guiding anesthetic or opioid administration, and (3) technical characteristics, including signal delay and pharmacodynamic modeling implications. Results: Sixteen studies met inclusion criteria. Eight validation studies demonstrated that IoC/qCON correlates strongly with clinical sedation scales and established EEG-derived indices such as BIS and entropy. Five interventional studies evaluating drug titration found limited impact of qCON-guided hypnosis control on anesthetic consumption but more consistent effects of qNOX/IoC2 guidance on opioid dosing and intraoperative stability. Three technical investigations showed that qCON exhibits processing delays on the order of tens of seconds that can be accounted for by incorporating monitor lag into pharmacodynamic analyses. Conclusions: qCON and qNOX provide complementary EEG-based indices of hypnosis and cortical nociceptive responsiveness. Evidence supports their validity as indicators of anesthetic brain state but highlights technical limitations, such as processing delay and susceptibility to physiologic factors. Their optimal clinical use lies in multimodal monitoring strategies that integrate EEG besides classic clinical and monitoring parameters. Full article

Background/Objectives: Prophylactic mastectomy can significantly reduce the risk of breast cancer in patients carrying gene mutations such as BRCA1 and BRCA2. Patients who opt for breast removal are offered tailored reconstructive options based on their medical history and prior treatments, and in these often young patients with limited autologous tissue reserves, implant-based reconstruction is frequently the option of choice. Complication rates of these procedures are relatively high and account for up to 30%. Subcutaneous mastectomy with primary implant reconstruction carries risks such as hematoma, seroma, skin necrosis, necrosis of the nipple–areola complex, and wound healing issues, which may necessitate revision surgery. This university-center retrospective analysis aims to improve outcomes by identifying patient- and surgery-related risk factors associated with postoperative complications in allogenic breast reconstruction following subcutaneous mastectomy. Methods: We analyzed 61 female patients and 122 breasts who underwent primary implant-based reconstruction after skin- or nipple-sparing subcutaneous mastectomy over three years between January 2021 and December 2023. Demographic and surgical variables were systematically collected and analyzed. Results: The mean patient age was 41.5 ± 10.3 years. A total of 13% of patients were active smokers, and 1.6% had diabetes mellitus. Overall, skin flap necrosis occurred in 27.9% of patients (22.1% of breasts), wound healing disorders in 19.7% of patients, wound infections in 9.8%, and revision surgery in 18.0%. A history of pregnancy was associated with skin flap necrosis (OR 10.07, 95% CI 1.79–190.06; p = 0.032); however, this finding must be interpreted with caution due to limited statistical power and model instability. Conclusions: This investigation revealed clinically relevant patterns suggesting potential risk factors for wound healing disorders and skin necrosis. Prospective studies are planned to further substantiate these findings and to help reduce overall complication rates associated with the procedure. Full article

Background: HyperCKemia, defined as elevated serum creatine kinase, commonly reflects muscle injury but may also indicate underlying metabolic disease. Metabolic aetiologies, including glycogen storage disorders, fatty acid oxidation defects, mitochondrial cytopathies, and purine metabolism disorders, are clinically important owing to diagnostic complexity, therapeutic implications, and potential reversibility. Objective: To summarise current evidence on metabolic causes of hyperCKemia in adults, with emphasis on disorders of carbohydrate, lipid, and purine metabolism and mitochondrial disease. Methods: Semi-systematic narrative review of pathophysiology, clinical features, diagnostic approaches, and management of metabolic disorders associated with hyperCKemia. Results: Metabolic myopathies often present with nonspecific or exercise-related symptoms, with creatine kinase levels ranging from mild-to-severe elevations. Conditions such as McArdle disease, carnitine palmitoyltransferase II deficiency, and mitochondrial cytopathies demonstrate characteristic metabolic vulnerabilities leading to episodic or persistent hyperCKemia. Medications, including statins and antiretrovirals, may precipitate symptoms in predisposed individuals. Diagnosis requires a structured, multidisciplinary approach incorporating biochemical testing, genetic analysis, functional studies, and muscle biopsy. Many causes are amenable to targeted therapy, including dietary modification, endocrine correction, and medication withdrawal. Conclusion: Metabolic causes of hyperCKemia are under-recognised but clinically significant. Early identification allows targeted treatment and prevention of complications. Full article

Objectives: Medication adherence in elderly patients is shaped by cognitive, behavioral, systemic, and socioeconomic factors. This review aimed to identify determinants and effective strategies to improve adherence in older adults. Methods: A systematic search of PubMed, Scopus, and ScienceDirect (2015–2025) followed PRISMA 2020 guidelines. From 5116 records, 53 studies met inclusion criteria. Randomized controlled trials were meta-analyzed using standardized mean differences under a random-effects model. Risk of bias in the 10 pooled trials was assessed using the Cochrane RoB 2 tool, and certainty of evidence was evaluated using the GRADE framework. Results: Adherence ranged from 25.3% in institutionalized patients to 97.6% in pharmacist-led schizophrenia programs. Cognitive impairment and frailty reduced adherence (54.2%), while caregiver involvement improved rates, especially in dementia and schizophrenia (77.4–97.6%). Socioeconomic barriers, including medication cost, contributed to nonadherence but were mitigated by subsidies. Digital tools enhanced adherence in chronic disease, and machine learning models accurately predicted nonadherence (AUC up to 0.935). Effective interventions—caregiver support, digital platforms, and single-pill regimens—increased adherence by 25–59% and reduced cardiovascular events. The meta-analysis demonstrated a significant pooled effect (Standardized Mean Difference, SMD = 0.71, 95% CI: 0.11–1.54), although heterogeneity was high (I² = 99%). The RoB 2 assessment of the 10 pooled trials identified 2 at low risk, 4 with some concerns, and 4 at high risk of bias; the GRADE certainty of evidence was rated Very Low. Conclusions: Multiple factors, including frailty, cognitive deficits, socioeconomic barriers, regimen complexity, and the level of caregiver support, appear to be consistently associated with medication adherence in older adults. Strategies such as caregiver engagement, digital health tools, regimen simplification, and mental health support may contribute to improved adherence, although effect sizes vary considerably across study contexts. Given the substantial heterogeneity, Very Low certainty of evidence (GRADE), and variable study quality, findings should be interpreted with caution. System-level reforms, financial assistance programs, and culturally tailored approaches may further support adherence, while the successful implementation of digital health solutions will require addressing literacy, accessibility, and integration challenges.

Background: Sinonasal mucosal melanoma is a rare and aggressive malignancy arising from the nasal cavity and paranasal sinuses, characterized by high local recurrence rates and poor survival. Skull-base and orbital progression can occur rapidly, particularly when preoperative imaging underestimates local extension. This paper reports a case of sinonasal mucosal epithelioid melanoma with fulminant postoperative skull-base breach and orbital invasion, highlighting its clinical course, management challenges, and histopathological features. Methods: A 60-year-old woman with progressive unilateral nasal obstruction, recurrent epistaxis, and headache underwent clinical evaluation, contrast-enhanced head MRI, CT, and PET-CT staging. Preoperative imaging demonstrated no intracranial or orbital invasion. Biopsy confirmed mucosal epithelioid melanoma with high proliferative activity (Ki-67 ~80–85%). The patient underwent extensive image-guided endoscopic resection with intraoperative cerebrospinal fluid leak repair. Results: Definitive histopathology confirmed pigmented epithelioid melanoma with extensive necrosis, bone invasion, and non-assessable resection margins due to specimen fragmentation (pT4a, Rx). Within two weeks postoperatively, CT and MRI demonstrated extensive local recurrence with cribriform plate destruction, anterior skull-base dural infiltration, and rapid orbital progression with optic nerve compression and loss of vision. Despite hemorrhage control and hypofractionated palliative radiotherapy (VMAT, 33 Gy in 11 fractions), the patient experienced progressive neurological decline, refractory pain, and recurrent tumour bleeding, and died approximately 4.5 months after initial presentation. Conclusions: In patients with sinonasal mucosal epithelioid melanoma, fulminant local progression with skull-base and orbital involvement may occur despite apparently limited preoperative imaging. When rapid vision loss, dural infiltration, and refractory nasal bleeding develop, structured palliation, hemorrhage control, and aggressive multimodal analgesia should be prioritized early alongside ongoing multidisciplinary decision-making.

Background: Mood disorders such as postpartum blues, anxiety disorders, perinatal depression and posttraumatic stress disorder are common and can take various forms. For this reason, the assessment of emotional disorders and quality of life in women should be an integral part of health monitoring, and this was therefore adopted as the aim of the present study. Methods: The study was conducted using a diagnostic survey with questionnaires based on the authors’ survey, the SF-36, and the Patient Health Questionnaire-9. The cross-sectional study was conducted among 400 women in Poland, including 172 pregnant and 228 postpartum women. Results: Negative correlations were found between the PHQ-9 and SF-36 in pregnant and postpartum women. Selected obstetric factors were shown to significantly influence SF-36 and PHQ-9 scores (p < 0.05). Conclusions: The risk of mood disorders is associated with the duration of attempts to conceive, the course of pregnancy, and the number of hospitalizations. The presence of depressive symptoms affects the quality of life of women during the perinatal period. Full article

Background and objectives: Head and neck cancer patients frequently undergo radiotherapy, which can affect the properties of dental hard tissues. This study aimed to evaluate the effects of root canal treatment, radiotherapy, and sonic activation during irrigation on the fracture resistance of mandibular anterior teeth. Methods: 80 extracted mandibular anterior teeth were randomly divided into five groups: untreated control (Group I); root canal treatment without radiotherapy or sonic activation (Group II); root canal treatment without radiotherapy but with sonic activation (Group III); root canal treatment with 70 Gray (Gy) radiotherapy and sonic activation (Group IV); and root canal treatment with radiotherapy but without sonic activation (Group V). Radiotherapy was administered in fractionated doses (2 Gy/day, 5 days/week) over 7 weeks. Following instrumentation, root canal obturation was performed accordingly. Fracture resistance was measured using a universal testing apparatus with vertical loading until fracture. Statistical analyses included Shapiro–Wilk normality testing followed by appropriate non-parametric Kruskal–Wallis test followed by Dunn’s post hoc test with Bonferroni correction for multiple comparisons. Results: All root canal-treated groups exhibited significantly lower fracture resistance compared to the untreated control group [1572.3 (1217.0–1841.2) N, p < 0.05]. No statistically significant differences were observed between irradiated and non-irradiated groups (p > 0.05). Similarly, sonic activation during irrigation did not significantly affect the fracture resistance values (p > 0.05). Conclusions: Under the specific conditions of this in vitro protocol, fractionated radiotherapy and sonic activation did not demonstrate statistically significant effects on fracture resistance in mandibular anterior teeth, while endodontic procedures reduced fracture resistance.

Background: Sexual dysfunction (SD) and sleep disturbances are frequent but underrecognized non-motor symptoms in Parkinson’s disease (PD) and significantly affect quality of life. However, the relationships among sexual dysfunction, sleep quality, and excessive daytime sleepiness (EDS) and the possible sex-related differences remain insufficiently investigated. Methods: In this cross-sectional case–control study, we evaluated these non-motor symptoms in 147 Turkish patients with PD and 160 age- and sex-matched healthy controls, and we assessed their associations and impact on quality of life, with particular attention to sex-specific patterns. Sexual function was assessed using the Arizona Sexual Experiences Scale (ASEX), sleep quality using the Pittsburgh Sleep Quality Index (PSQI), daytime sleepiness using the Epworth Sleepiness Scale (ESS), quality of life using the 39-item Parkinson’s Disease Questionnaire (PDQ-39), and disease severity using the Unified Parkinson’s Disease Rating Scale (UPDRS) and Hoehn and Yahr (H&Y) staging scale. Group comparisons, correlation analyses, and sex-stratified subgroup analyses were performed. Results: Patients with PD had significantly higher ASEX, PSQI, and ESS scores compared with controls (p < 0.01), and women with PD had significantly higher total ASEX scores than men, indicating greater sexual dysfunction. Sexual dysfunction was significantly associated with poor sleep quality and excessive daytime sleepiness but showed no significant association with the motor severity measures (UPDRS, H&Y stage). Sleep quality, as measured via PSQI scores, was worse in patients with PD, and poor sleep quality and excessive daytime sleepiness were both associated with significantly worse quality of life. Conclusions: According to our findings, sexual dysfunction and sleep disturbances are interrelated non-motor symptoms that significantly impair quality of life, largely independently of motor severity, and these associations were particularly pronounced among women. A combined evaluation of sleep and sexual function may therefore improve the recognition and management of the non-motor burden in PD. Full article

Background: Diabetic foot osteomyelitis (DFO) is a severe complication requiring effective empiric antibiotic therapy to prevent amputation. While global guidelines suggest tailoring therapy based on climate zones, limited data exist regarding seasonal variations within a single region experiencing distinct seasonal extremes. This study investigated whether the bacterial etiology of DFO differs significantly between the hot, humid summer and the cold, dry winter in the Republic of Korea. Methods: We conducted a retrospective cohort study of 85 patients with DFO who underwent lower extremity amputation between January 2018 and October 2024. Patients were categorized into Summer (July–August) and Winter (December–January) groups. Deep tissue or bone specimens were analyzed to compare pathogen prevalence. Results: A total of 85 patients were included (Summer: n = 45; Winter: n = 40). While Staphylococcus species were the most common pathogens overall (30.6%), a seasonal shift was observed. The proportion of Gram-negative isolates was higher in Summer (50.7%) compared to Winter (35.1%), representing a notable clinical trend (p = 0.080). Specifically, Pseudomonas aeruginosa and Escherichia coli were more frequently isolated during the summer months. Furthermore, polymicrobial infections were more prevalent in Summer (62.2%) compared to Winter (45.0%), although this did not reach statistical significance (p = 0.111). Conclusions: The microbiological profile of DFO exhibits seasonal variations. The observed trend toward an increased prevalence of Gram-negative and polymicrobial infections during the Korean summer suggests that empiric antibiotic guidelines should be dynamic rather than static.

Background/Objectives: Shear wave elastography (SWE) has emerged as a quantitative imaging technique for assessing muscle mechanical properties and has been increasingly applied to post-stroke spasticity. However, the clinical validity of SWE relative to established clinical spasticity scales and the influence of assessment protocols remain incompletely understood. This systematic review and meta-analysis aimed to evaluate the clinical validity of SWE for post-stroke spasticity and to identify clinically relevant methodological moderators. Methods: A systematic literature search was conducted in PubMed, Cochrane Library, CINAHL, and Web of Science to identify studies reporting correlations between SWE measures and clinical spasticity scales in individuals with stroke. Random-effects meta-analyses were performed using robust variance estimation to account for dependent effect sizes within studies. Prespecified subgroup and meta-regression analyses examined potential moderators, including clinical scale, muscle position during assessment, output metric, limb segment, and stroke chronicity. Results: Ten studies involving 303 participants contributed 38 correlation estimates. The pooled correlation between SWE and clinical spasticity scales was moderate (r = 0.42, 95% CI 0.34–0.49). SWE demonstrated significantly stronger correlations with the Modified Tardieu Scale than with the Modified Ashworth Scale. Measurements obtained in stretched muscle positions showed higher validity than those obtained at rest. Other examined moderators were not statistically significant. No evidence of publication bias was detected. Conclusions: SWE shows a moderate association with clinician-rated spasticity scales and appears to reflect the mechanical consequences of post-stroke spasticity. Associations were influenced by scale selection and measurement position. These findings support protocol-informed integration of SWE as a quantitative adjunct for assessing passive muscle stiffness rather than as a replacement for established clinical scales.

Background: The risk of morbidity and mortality increases in newborns requiring postpartum transport. Various scoring systems have been developed to determine mortality risk, such as the Transport Risk Index of Physiologic Stability (TRIPS) and Mortality Index for Neonatal Transportation (MINT) scores. This study aimed to evaluate the efficiency of MINT and TRIPS scores by comparing them with the Score for Neonatal Acute Physiology-Perinatal Extension (SNAPPE-II) scoring system in preterm and term infants transported within the first 24 h after birth. Methods: This retrospective study included neonates transported within the first 24 h of life to the NICU of Etlik Zübeyde Hanım Women’s Health Training and Research Hospital between 2016 and 2021, following ethics approval. Perinatal data, admission clinical and laboratory parameters, and TRIPS, MINT, and SNAPPE-II scores calculated within the were recorded. Mortality and short-term morbidities were analysed. Group comparisons were conducted using Mann–Whitney U and chi-square tests. Predictive performance and optimal cut-off values were determined by receiver operating characteristic curve analysis using the Youden index. p value <0.05 was considered significant. Results: A total of 137 newborns were included in the study. Seventy-two cases (52.6%) were preterm, and 65 cases (47.4%) were term newborns. The median gestational age and birthweight were 35.6 weeks and 2485 g, respectively. A total of 10 patients died. For mortality prediction, the areas under the curve for TRIPS, MINT, and SNAPPE-II were 0.919, 0.907, and 0.973, respectively (p < 0.001). The determined cut-off values for TRIPS, MINT, and SNAPPE-II were >19, >4, and >35, respectively. The TRIPS score showed the best accuracy for prediction of mortality in preterm infants. Conclusions: Our data show that MINT and TRIPS scores are efficient beyond SNAPPE-II. They demonstrated high diagnostic effectiveness in predicting mortality in preterm and term infants. The TRIPS score exhibits superior mortality prediction in preterm infants. Full article

Sepsis and septic shock remain major causes of morbidity and mortality in critically ill patients. Hemodynamic management is a cornerstone of treatment, yet the optimal monitoring strategy to guide resuscitation is still debated. The progressive decline in the use of invasive techniques, such as pulmonary artery catheterization, has favored the development of less-invasive and non-invasive monitoring approaches. Recent technologies allow continuous assessment of cardiovascular function through arterial waveform analysis, non-invasive blood pressure monitoring, and predictive algorithms, while increasing attention has been directed toward the evaluation of tissue perfusion and oxygenation. This reflects the recognition that normalization of macrocirculatory variables does not necessarily ensure adequate microcirculatory perfusion in sepsis. This narrative review summarizes current evidence on less-invasive hemodynamic and tissue perfusion monitoring in sepsis and septic shock, discussing their physiological rationale and potential role within contemporary, multimodal resuscitation strategies.

Background: Senior–Loken syndrome (SLS) is a rare autosomal recessive ciliopathy classically defined by the concurrence of nephronophthisis, frequently progressing to end-stage renal disease (ESRD), and retinal dystrophy, most commonly presenting as retinitis pigmentosa (RP). Given its phenotypic overlap with other renal–retinal syndromes, establishing a definitive diagnosis necessitates integrated clinical evaluation and molecular confirmation. Case Presentation: A 28-year-old Chinese female presented with a two-month history of binocular floaters. Her medical history was significant for ESRD of five years’ duration, managed with maintenance hemodialysis. Ophthalmic assessment revealed retinal pigment mottling along the inferior temporal arcades and generalized arterial attenuation. Spectral-domain optical coherence tomography demonstrated outer retinal thinning with loss of the ellipsoid zone at corresponding locations. Perimetry confirmed visual field constriction, and full-field electroretinography showed severely reduced rod- and cone-mediated responses. Genetic testing was performed and a pathogenic variant in the NPHP1 gene was identified. Segregation studies confirmed both parents as heterozygous carriers, consistent with autosomal recessive inheritance. Collectively, these findings established a diagnosis of SLS. Conclusions: This case reinforces that SLS should be considered in the differential diagnosis of any young patient exhibiting RP alongside chronic kidney disease, particularly in the setting of early-onset ESRD. It also illustrates the essential role of a coordinated, multidisciplinary approach—encompassing nephrology, ophthalmology, and genetics—in diagnosing complex ciliopathies. Genetic confirmation not only validates the clinical diagnosis but also provides a foundation for family counseling, prognostic stratification, and future eligibility for gene-specific therapeutic trials.
