Background and Objectives: Perforated peptic ulcer (PPU) is an emergent condition managed by surgical intervention. No conclusive evidence has been produced regarding the need for drain placement after primary repair. Our meta-analysis aimed to provide insight into the short-term outcomes by comparing the two strategies of drain omission or intra-operative placement of at least one drain. Materials and Methods: We performed a systematic review following the PRISMA guidelines. PubMed/MEDLINE, Web of Science, Cochrane Library, and Embase databases were utilized to identify articles of interest. Meta-analysis was performed using RevMan Version 5.4. Eligible studies were comparative studies (RCTs and observational studies) enrolling adult patients (≥18 years) undergoing emergency primary repair for PPU, with or without prophylactic intra-abdominal drain placement; case reports and series of fewer than 10 patients were excluded. The literature search covered January 2010 to 22 February 2026. Risk of bias was assessed using the Cochrane RoB 2.0 tool for RCTs, and the ROBINS-I V2 tool for observational studies; certainty of evidence was graded using the GRADE framework. Pooled effect estimates were calculated using a random-effects model and expressed as odds ratios (OR) or mean differences (MD) with 95% confidence intervals (CI); statistical heterogeneity was quantified using the I² statistic. Results: Five studies were considered for comparison, for a total of 1354 patients (744 and 610 in the drain and no-drain groups, respectively). Three were randomized controlled trials, and two were retrospective cohort studies, conducted across four countries (India, the USA, Egypt, and Japan). Meta-analysis of the pooled results showed that drain omission was associated with a shorter length of stay (LOS) (MD −2.13, 95% CI [−3.91–−0.35], p < 0.0001) and a lower rate of superficial surgical site infections (SSIs) (16.7% vs. 52.7%, OR 0.24, 95%CI [0.11–0.55], p = 0.0007). No difference was observed regarding the rate of leaks, reoperation, or deep SSIs. Low-certainty evidence suggested higher postoperative mortality in the no-drain group (OR: 1.96; 95% CI: 1.10 to 3.48; p = 0.02; I² = 0%), largely driven by retrospective studies with a high risk of bias. This mortality finding is of very low certainty and is most likely attributable to confounding in the observational studies rather than a true causal effect of drain omission. Several outcomes were based on data from only two to three studies, and the overall certainty of evidence was low to very low. Conclusions: Drain omission after primary repair for PPU may be associated with better outcomes in terms of LOS and superficial SSIs, primarily in lower-acuity patients, as reflected by the inclusion criteria of the contributing RCTs. Pooled analysis showed a higher postoperative mortality in the no-drain group; however, given the significant biases among included studies, our results should be interpreted as non-causal and thus require careful interpretation. Further research encompassing the full clinical spectrum of PPU is needed to confirm our results. Evidence certainty was low to very low across all outcomes, primarily due to a risk of bias, high heterogeneity (I² up to 95% for LOS), indirectness, and imprecision. Full article

Background and Objectives: Obstructive sleep apnea (OSA) is a common disorder associated with significant cardiovascular, metabolic, and neurocognitive consequences. The STOP and STOP-BANG questionnaires are widely used screening tools for identifying individuals at increased risk of OSA. However, their performance may vary across populations. This variability is due to demographic and anthropometric differences. We aimed to analyze the screening accuracy of the STOP and STOP-BANG questionnaires across three distinct Mediterranean populations: Croatia, Greece, and Türkiye. Additionally, we aimed to optimize and establish population-specific cut-off points for body mass index (BMI) and neck circumference (NC) in the questionnaires to enhance their screening accuracy. Materials and Methods: A total of 9102 patients who underwent polysomnography or polygraphy to evaluate suspected OSA were enrolled from: Split Sleep Medicine Centre (Croatia), Ege University Faculty of Medicine (Türkiye), and Thessaloniki G Papanikolaou Hospital Aristotle University (Greece). Patients completed the STOP and STOP-BANG questionnaires before sleep assessments. Sensitivity, specificity, and the area under the receiver operating characteristic (ROC) curve (AUC) were calculated to assess the screening properties. Additionally, optimized cut-offs for age, NC, and BMI were determined. Results: The highest AUC values were observed using the STOP-BANG ≥ 5 method, with AUC values of 0.712 for detecting any OSA (AHI ≥ 5/h), 0.684 for moderate or severe OSA (AHI ≥ 15/h), and 0.663 for severe OSA (AHI ≥ 30/h). For individual centers, the STOP-BANG ≥ 5 method performed best in Split, while the STOP ≥ 2 + NC method yielded the highest AUCs in Izmir and Thessaloniki for moderate and severe OSA. Optimized cut-off values for age, NC, and BMI improved sensitivity and specificity across all centers. Conclusions: This study highlights the need for population-specific considerations in the screening for OSA. Significant differences in demographics, anthropometrics, symptoms, and comorbidities across populations could impact the questionnaire’s screening accuracy. Adjusting age, NC, and BMI cut-off points optimizes the STOP-BANG questionnaire. Full article

Background and Objectives: Endometriosis is a multifactorial gynecological condition associated with impaired fertility; however, its impact on embryo competence remains incompletely understood. This study aimed to evaluate embryo competence through a stepwise analysis of IVF outcomes across the developmental continuum, while also comparing patients with endometriosis and controls. Materials and Methods: A retrospective observational study was conducted, including 160 patients undergoing IVF, comprising 55 patients with endometriosis and 105 controls. Clinical and embryological data were analyzed sequentially across key developmental stages, including oocyte retrieval, metaphase II (MII) oocyte formation, fertilization (2PN), embryo development, and euploidy in a subgroup undergoing preimplantation genetic testing for aneuploidy (PGT-A). Stage-specific efficiency rates were calculated, and correlations between early- and late-developmental parameters were assessed. In addition, comparative analysis between groups was performed. Results: A progressive decline in developmental efficiency was observed across the IVF continuum, with approximately one-quarter of retrieved oocytes reaching the embryo stage and only a small proportion ultimately resulting in euploid Blastocysts. Strong positive correlations were identified among early-stage parameters, particularly retrieved oocytes, MII oocytes, and embryo yield (r = 0.77–0.96, p < 0.001), indicating that ovarian response and oocyte maturity significantly influence downstream outcomes. However, efficiency-based parameters showed limited predictive value for chromosomal competence. A moderate association was observed between MII oocytes and euploid Blastocysts (r = 0.58), whereas the relationship between embryo number and euploidy remained weak. Comparative analysis revealed no statistically significant differences between the endometriosis and control groups across the evaluated embryological parameters (p > 0.05 for all comparisons), suggesting that sequential analyses may provide complementary insight beyond direct comparisons. Conclusions: IVF outcomes follow a sequential developmental trajectory with a progressive decline in efficiency across stages. In endometriosis, early developmental competence appears to be affected, while chromosomal competence remains relatively preserved. Full article

Background and Objectives: Although clinically useful, homologous recombination deficiency (HRD) testing has recently been more broadly adopted in ovarian cancer (OC) management. The VALIDATE study evaluated HRD status and treatment patterns in patients with newly diagnosed advanced OC in Bulgaria to better understand HRD prevalence and disease management. Materials and Methods: This real-world, observational, multi-centre, medical chart review study included 100 adult patients with HRD testing results available at study entry. Data collected at least 30 days after HRD results and 6 months later were descriptively analysed in the full cohort and subgroups (HRD, BRCA mutation, and genomic instability score [GIS]). Results: Mean age at diagnosis: 61.3 years; stage III: 51.0%, prevalence of HRD+ 58.0% (95% confidence intervals [CI] 47.7–67.8%) and HRD− 42.0% (95% CI 32.2–52.3%). Among the 58 HRD+ patients, 20 (34.5%) were BRCA+, whereas 38 (65.5%) were BRCA−, and 52 (89.7%) were GIS+, and 6 (10.3%) GIS−. Overall, platinum–taxane chemotherapy plus antiangiogenics was the most common front-line (FL) treatment (77.0%), regardless of subgroups (range: 66.7–85.0%). Six months later, 81 patients were alive, and 73 (90%) started maintenance therapy (MT). Antiangiogenic monotherapy (32.0%) and antiangiogenic plus PARP inhibitor (34.0%) were the most common MTs. The latter was also common across subgroups (range: 33.3–60.5%), except for HRD− (61.9% received antiangiogenic monotherapy). Conclusions: In this dataset, more than half of advanced OC patients had HRD+ status. Our study provides relevant insights into recent clinical practice patterns in advanced OC in Bulgaria that could serve as an anchor for future, more robust research in this field. Full article

Background and Objectives: Temporomandibular disorders (TMDs) are heterogeneous conditions whose clinical expression cannot be fully explained by local or structural findings alone. DC/TMD Axis II provides a psychobehavioral framework for assessing pain, disability, jaw functional limitation, psychological symptoms, and oral behaviors. This conceptual narrative review aimed to clarify how oral behaviors, anxiety, and depressive symptoms can be clinically interpreted together within the DC/TMD Axis II framework. Materials and Methods: A structured search was conducted in PubMed/MEDLINE and Scopus, with records exported in March 2026. Eligible English-language publications were limited to January 2001–March 2026. Google Scholar was used as a supplementary verification source. After deduplication, 2756 records were screened, 87 full-text reports were assessed, and 36 publications were included in the final narrative synthesis. Evidence was synthesized thematically and appraised according to study design, population, diagnostic framework, Axis II instruments, self-report reliance, confounding, and inferential strength. Results: Current literature supports associations between oral behaviors, anxiety, depressive symptoms, pain intensity, and mandibular functional limitation in TMD, especially in painful and functionally impaired profiles. These associations are not uniform across all TMD subtypes and are influenced by factors such as sex, pain burden, comorbidities, and psychosocial context. The Oral Behaviors Checklist is useful for standardizing self-reported oral behaviors, but its interpretation is limited by recall, awareness, and reporting bias. Conclusions: The reviewed evidence supports an interactional interpretation of oral behaviors, psychological symptoms, pain, and jaw function within the DC/TMD Axis II framework. However, because most available studies are cross-sectional and self-reported, this model should be understood as a clinically informed hypothesis supported by convergent associations, not as a confirmed causal pathway. Longitudinal and intervention-based studies are needed to clarify directionality, prognosis, and treatment-response relevance. Full article

Background and Objectives: Small bowel obstruction (SBO) is a common surgical emergency, accounting for 15–20% of acute general surgical admissions. Despite the Bologna Guideline’s introduction to the surgical community almost a decade ago, adherence to it remains variable. The therapeutic role of contrast media and the optimal timing of its administration remain a matter of debate. This study aimed to compare SBO resolution rates according to the timing of water-soluble contrast media (WSCM) administration. Materials and Methods: A prospective, randomised pilot trial was conducted at two regional hospitals in Estonia. Patients hospitalised with adhesive or virgin abdomen SBO were randomised to receive WSCM at either 4 h or 24 h after admission. Results: A total of 128 patients were enrolled, with 63 assigned to the 4 h group and 65 to the 24 h group. SBO resolved with conservative management in 74.6% of patients in the 4 h group and 73.8% in the 24 h group. Rates of surgical intervention and bowel resection due to necrosis were comparable between groups. Univariable and multivariable analyses showed no significant association between early administration and improved resolution. A prior history of SBO was associated with a higher likelihood of successful non-operative management. Conclusions: conservative management of SBO is safe and effective, and early WSCM administration did not provide a clear additional benefit in this cohort with respect to resolution or surgical outcomes. A prior history of SBO was associated with a higher likelihood of successful conservative management in this cohort. Larger multicentre studies are warranted to further define the optimal timing of contrast administration and to compare isotonic and hyperosmolar agents with respect to clinical outcomes.

Background and Objectives: This study evaluated the effect of two wound closure methods—polypropylene sutures and a butyl-2-cyanoacrylate tissue adhesive—on the rate of soft tissue regeneration following palatal donor site harvesting. A bovine collagen sponge, used as a secondary-intention dressing, was evaluated descriptively. Materials and Methods: Data from 300 patients (n = 100/group) with palatal donor sites were analyzed. Primary analysis compared suture vs. adhesive using Early Wound Healing Score (EHS) at days 7 and 14. Secondary outcomes were granulation tissue (day 7) and complications. Statistical methods: Mann–Whitney U test for between-group comparison (suture vs. adhesive); Kruskal–Wallis with Dunn’s post hoc for granulation across all three groups; Spearman’s correlation and logistic regression for the relationship between granulation tissue and EHS within primary healing groups. Results: At day 7, median EHS was similar between suture and adhesive groups (7.0 [interquartile range (IQR) 5.0–9.0] vs. 7.0 [IQR 7.0–9.0]; p = 0.31). By day 14, both groups achieved excellent healing (median 10.0, IQR 9.0–10.0 in both; p = 0.82). The collagen sponge group showed slower healing (median EHS day 7 = 4.0 [IQR 3.0–5.0], day 14 = 6.0 [IQR 5.0–7.0]), reported descriptively as expected for secondary intention. Granulation tissue on day 7 was highest in the adhesive group (p < 0.001 vs. collagen; p = 0.024 vs. suture). A strong positive correlation between day-7 granulation tissue and day-14 EHS was found in the primary-healing groups (ρ = 0.78, p < 0.001). Receiver operating characteristic (ROC) analysis established a granulation score ≥ 2 as the optimal cut-off for predicting successful healing (EHS ≥ 9) by day 14 (sensitivity 89.4%, specificity 76.0%, area under the curve (AUC) = 0.80), pending external validation. Conclusions: Surgical adhesive may be considered a viable alternative to sutures for palatal donor sites closed by primary intention, offering comparable healing by day 14. Collagen sponges result in slower healing and should be considered only when secondary intention is specifically desired. Early assessment of granulation tissue may serve as a simple prognostic indicator, but external validation is needed before clinical application. Full article

Background and Objectives: Pulmonary hypertension (PH) remains associated with substantial mortality despite advances in treatment. Although prognostic factors have been widely described at sea level, their behavior in populations living at high altitude remains insufficiently characterized. This study aimed to identify factors associated with mortality during follow-up in patients with Group 1 PH residing at high altitude. Materials and Methods: A retrospective cohort study was conducted including patients with confirmed Group I PH diagnosed by right heart catheterization and treated between 2017 and 2022. Clinical, functional, and hemodynamic variables were analyzed. A penalized logistic regression model using Elastic Net methodology was applied to identify variables associated with five-year mortality. Results: A total of 165 patients were included, with a mean age of 41 years (SD 13.93), and 84.2% were women. Among PH etiologies, congenital heart disease was the most frequent cause (50.3%), followed by idiopathic PH (33.3%) and connective tissue disease-associated PH (12.7%). Five-year mortality was 13.3% (22/165). Idiopathic pulmonary hypertension was significantly more frequent among deceased patients compared to survivors (13/22 [59.1%] vs. 42/143 [29.4%], p = 0.025). Mortality was associated with acute pulmonary embolism, greater smoking burden, worse functional class, and adverse hemodynamic parameters. In multivariable analysis, acute pulmonary embolism (coefficient 0.196; OR 1.216; 95% CI 1.16–1.27; p < 0.001), ESC/ERS risk stratification (coefficient 0.158; OR 1.171; 95% CI 1.08–1.26; p < 0.001), pulmonary vascular resistance > 25 wood units (coefficient 0.180; OR 1.198; 95% CI 1.13–1.26; p < 0.001), and age ≥ 65 years (coefficient 0.171; OR 1.187; 95% CI 1.10–1.27; p < 0.001) were identified as risk factors, while female sex showed a protective effect (coefficient −1.041; OR 0.353; 95% CI 0.33–0.37; p < 0.001). Conclusions: In patients with Group 1 PH living at high altitude, several clinical, functional, and hemodynamic variables were associated with increased mortality, including acute pulmonary embolism, elevated pulmonary vascular resistance, advanced age, and intermediate-high risk stratification. Female sex was associated with lower mortality. Full article

Background and Objectives: Healthcare-associated infections (HAIs) remain a major cause of morbidity and mortality among hospitalized patients. During the COVID-19 pandemic, SARS-CoV-2 infection emerged as a major contributor to HAIs, alongside Clostridioides difficile infection (CDI) and other bacterial infections. This study aimed to evaluate the clinical characteristics and outcomes of HAIs in surgical departments and to identify factors associated with in-hospital mortality. Materials and Methods: We conducted a retrospective observational study including 170 patients with documented HAIs admitted between July 2018 and June 2022 in surgical departments of a county emergency hospital. Patients were categorized into SARS-CoV-2 infection (n = 85), CDI (n = 73), and other bacterial infections (n = 12), the latter being included for descriptive purposes only due to limited sample size. Clinical variables, comorbidities, prior antibiotic exposure, length of hospital stay, and in-hospital mortality were analyzed. Survival analysis and logistic regression were performed to identify predictors of mortality. Results: SARS-CoV-2 infection represented the largest subgroup, followed by CDI. Overall, in-hospital mortality was 15.9%, with comparable rates between SARS-CoV-2 infection (17.6%) and CDI (16.4%), while no deaths were observed in the small subgroup of other bacterial infections. CDI patients had a significantly higher burden of comorbidities (p = 0.004). Kaplan–Meier analysis did not show a statistically significant difference in survival between SARS-CoV-2 and CDI groups (log-rank p = 0.28). In univariate analysis, acute respiratory failure (OR ≈ 13.5, p < 0.001), chronic kidney disease (OR ≈ 4.4, p = 0.018), and number of comorbidities (p = 0.019) were associated with mortality, but none remained significant in multivariable analysis. Conclusions: In-hospital mortality was similar between SARS-CoV-2 infection and CDI, highlighting the persistent clinical impact of CDI in hospitalized patients. Comorbidity burden and acute complications, particularly respiratory failure, were key determinants of mortality. These findings highlight the persistent clinical impact of CDI and the role of comorbidity burden and acute complications, particularly respiratory failure, in shaping in-hospital mortality. The absence of independent predictors in multivariable analysis should be interpreted cautiously given the limited sample size. Full article

Background and Objectives: Knee osteoarthritis (KOA) is a degenerative joint disease that affects quality of life through pain, impaired functional performance, and altered gait patterns. Hydrotherapy is a well-tolerated form of physical rehabilitation, especially suitable for patients with severe pain, as water’s properties support movement while reducing joint load. Its effects have been widely studied, primarily focusing on patient-reported outcomes, with limited synthesis of functional performance and gait-related outcomes. Materials and Methods: A systematic search was conducted in PubMed, Web of Science, Cochrane, PEDro, SpringerLink, ScienceDirect, and Google Scholar, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The search strategy included a combination of Medical Subject Headings (MeSH) terms and keywords. For example, the PubMed search strategy was as follows: (“knee osteoarthritis” OR “knee OA”) AND (“hydrotherapy” OR “aquatic therapy” OR “water-based exercise”) AND (“gait” OR “walking” OR “functional performance”). Randomized controlled trials (RCTs) from the last 10 years involving patients with KOA undergoing aquatic therapy were included. Primary outcomes included functional performance assessed by measures such as the 6 min walking test (6MWT), the Timed Up and Go (TUG) test, the five sit-to-stand (5 STS) and stair climb (SC) tests, and by using gait-related parameters (e.g., speed, cadence, and step length) assessed clinically or using technology. Patient-reported outcomes, including the Visual Analog Scale (VAS), Western Ontario and McMaster University’s Osteoarthritis Index (WOMAC), and Knee Injury and Osteoarthritis Outcome Score (KOOS), were analyzed as a secondary objective. Results: A total of 479 studies were identified, of which 13 met the eligibility criteria. The results revealed improvements in functional performance, with increases in 6MWT in five studies, the TUG test in four trials, and better performance in the 5-STS and SC tests in five studies. Benefits in gait parameters were noted in four studies. Additionally, one of the articles reported improvements in static and dynamic balance, another showed enhanced proprioception, and a third described more efficient muscle activation during gait following hydrotherapy. Consistent benefits in pain reduction, joint stiffness, and activities of daily living, as reflected by VAS, WOMAC, and KOOS, were also noted immediately and maintained at follow-up. The variability in outcome measures and intervention characteristics limited the possibility of data integration and the calculation of effect sizes. Conclusions: Hydrotherapy as a rehabilitation intervention may be associated with improvements in functional capacity, mobility, and self-reported physical ability in patients with KOA, with some evidence supporting a beneficial effect on gait; however, the certainty of evidence remains low to moderate due to heterogeneity among studies and limited sample sizes. These findings should be interpreted in light of the methodological limitations identified across the included trials. Full article

Background and Objectives: SGLT2 inhibitors increase hemoglobin and hematocrit in multiple clinical settings, an effect increasingly attributed to stimulation of erythropoiesis rather than hemoconcentration. However, most mechanistic evidence derives from diabetic populations, leaving uncertainty as to whether this response depends on diabetes-related metabolic changes. To evaluate whether dapagliflozin stimulates erythropoiesis in non-diabetic patients with heart failure and to determine whether hematologic changes correlate with renal, cardiac, inflammatory, hepatic, or iron-related parameters. Materials and Methods: In this retrospective observational study, each of 68 non-diabetic heart failure patients served as their own control. Hematologic, renal, cardiac, inflammatory, hepatic, and iron parameters were assessed at three time points: one year prior to dapagliflozin initiation, at baseline, and one year after initiation of therapy. Changes were analyzed using paired tests and correlation analyses. Results: Hemoglobin, hematocrit, and red blood cell count were significantly lower at the baseline compared with values recorded one year before dapagliflozin initiation and increased significantly during the year following treatment (all p < 0.001), while mean corpuscular indices remained stable. Serum iron decreased before treatment and increased significantly after dapagliflozin initiation (p < 0.05 vs. baseline); however, changes in serum iron did not correlate significantly with changes in hemoglobin after treatment. Inflammatory markers showed a modest reduction in C-reactive protein after treatment, while composite inflammatory indices remained largely stable. Liver enzymes showed no significant longitudinal changes. Correlation analyses demonstrated no association between changes in hemoglobin and changes in eGFR (ρ = 0.202, p = 0.098) or NT-proBNP (ρ = −0.003, p = 0.981) after treatment. Hematologic variables remained strongly intercorrelated, whereas cross-system correlations were minimal, indicating that erythropoietic stimulation occurred largely independently of renal or cardiac functional trajectories. Conclusions: Dapagliflozin robustly stimulates erythropoiesis in non-diabetic patients with heart failure, independent of improvements in kidney or cardiac function. Although serum iron levels improved after treatment, the absence of a direct correlation with hemoglobin suggests that iron mobilization may act as a permissive rather than a primary driver of erythropoietic response. These findings support the concept that erythropoiesis represents a diabetes-independent pharmacologic action of SGLT2 inhibitors and may involve renal, hepatic, inflammatory, and iron-regulatory pathways beyond those described in diabetic physiology. Dedicated mechanistic studies in non-diabetic populations are warranted. Full article

Background and Objectives: Neoadjuvant chemotherapy (NAC) followed by radical cystectomy is the standard of care for eligible patients with locally advanced bladder cancer (LABC). However, adjuvant chemotherapy (AC) remains widely used in real-world practice. Host-related inflammatory and nutritional biomarkers may also influence survival outcomes. This study aimed to compare survival outcomes between NAC and AC and to identify independent prognostic factors for overall survival (OS) and progression-free survival (PFS), with particular emphasis on the Prognostic Nutritional Index (PNI). Methods: This multicenter retrospective study included 262 patients with locally advanced bladder cancer. The median age was 66 years, and 84% of patients were male. Patients were treated with neoadjuvant chemotherapy followed by radical cystectomy or adjuvant chemotherapy after surgery between August 2021 and March 2025. The Prognostic Nutritional Index (PNI) was calculated using pretreatment laboratory values. ROC analysis was used to determine the optimal PNI cut-off for predicting mortality, and the derived threshold (49.97) was applied for stratification in all survival analyses. Survival outcomes were evaluated using the Kaplan–Meier method and compared using the log-rank test. Multivariate Cox proportional hazards regression was used to identify independent prognostic factors. Results: Among 262 patients, 138 (52.7%) received NAC, and 124 (47.3%) received AC. Median follow-up was 33.6 months (95% CI: 29.4–37.8). No statistically significant differences in OS (p = 0.388) or PFS (p = 0.499) were observed between treatment groups. In univariate analyses, nodal stage, pathological complete response (pCR), and PNI were significantly associated with both OS and PFS. In multivariate analysis, low PNI (≤49.97) remained an independent predictor of mortality (HR 1.78, 95% CI 1.04–3.38; p = 0.044), while N3 nodal stage independently predicted disease progression (HR 5.92, 95% CI 1.06–32.84; p = 0.042). Conclusions: In this multicenter real-world cohort, nodal stage and systemic inflammatory-nutritional status were key determinants of prognosis in patients with locally advanced bladder cancer receiving perioperative chemotherapy. PNI emerged as an independent predictor of overall survival, suggesting that host-related biomarkers may improve prognostic stratification beyond traditional clinicopathological factors.

Background and Objectives: Cardiac implantable electronic device (CIED) infections remain among the most serious complications of pacemaker, implantable cardioverter-defibrillator, and cardiac resynchronization therapy procedures. They are associated with substantial morbidity, mortality, prolonged hospitalization, system extraction, long-term antimicrobial therapy, and increased healthcare costs. As most infections arise from perioperative contamination or procedure-related complications, prevention has become a major priority in contemporary electrophysiology practice. This review aimed to summarize current evidence on the prevention of CIED infections, with particular emphasis on modifiable risk factors and perioperative preventive measures. Materials and Methods: A focused narrative review was undertaken using targeted searches of PubMed/MEDLINE and Scopus, supplemented by major international guideline and consensus documents, with priority given to contemporary guidelines, randomised trials, meta-analyses, and major observational studies relevant to CIED infection prevention. Results: Prevention of CIED infection requires a structured, multifactorial approach spanning the entire procedural pathway. Key preventive strategies include careful reassessment of device indication, individualized device selection, correction of modifiable risk factors, postponement of elective implantation in the presence of active infection, appropriate perioperative antibiotic prophylaxis, and optimized management of anticoagulant and antiplatelet therapy to minimize pocket hematoma. Additional relevant measures include meticulous skin antisepsis, limitation of temporary invasive devices and unnecessary hardware, appropriate venous access selection, careful generator pocket creation and wound closure, and avoidance of early reintervention whenever feasible. Antibacterial envelopes may reduce major CIED infections in selected high-risk patients, whereas routine escalation of preventive measures without proven benefit is not supported. Conclusions: CIED infection prevention is inherently multifactorial and depends on the consistent application of evidence-based measures before, during, and after device implantation. Rigorous control of modifiable risk factors, prevention of pocket hematoma, appropriate antimicrobial prophylaxis, and meticulous procedural technique remain the cornerstones of effective infection prevention in patients undergoing CIED procedures.

Background and Objectives: Pericoronary adipose tissue (PCAT) attenuation measured on coronary CT angiography is a promising imaging biomarker of coronary inflammation; however, absolute values may be influenced by technical and inter-individual variability, and a standardized methodology for measurement has not been established. Our study aimed to evaluate the association between PCAT attenuation and CAC burden while comparing absolute attenuation values with normalized values to minimize these sources of variability. Materials and Methods: Two hundred patients undergoing cardiac CT were included and stratified into four CAC categories (0, 1–99, 100–299, ≥300). PCAT attenuation was measured at multiple locations on two main levels: aortic root level and four-chamber view level. Relative PCAT attenuation was calculated by subtracting subcutaneous fat attenuation from raw PCAT values. Group comparisons were performed using ANOVA or Kruskal–Wallis tests, and multivariable linear regression models were adjusted for age, sex, and body mass index. Results: In univariate analysis, relative PCAT attenuation differed significantly across CAC categories at the aortic-level right coronary artery (RCA) site (p = 0.007). In multivariable analysis, higher CAC categories were associated with increased relative PCAT attenuation at the aortic RCA (β = 8.56, p = 0.015 for CAC 100–299; β = 10.68, p = 0.005 for CAC ≥300), while associations at the left main coronary artery (LMCA) showed significance in low and moderate CAC categories (β = 6.91, p = 0.047 for CAC 1–99 and β = 8.57, p = 0.016 for CAC 100–299). No significant associations were observed between CAC and raw PCAT attenuation at the aortic level, while isolated and inconsistent findings were observed in other territories. Conclusions: Relative PCAT attenuation is independently associated with CAC severity and normalized values may reduce technical and biological variability, potentially enhancing the sensitivity and robustness of this CT-based biomarker.

Background and Objectives: Spondylodiscitis is a severe spinal infection associated with substantial mortality. Standard diagnostic imaging is often limited to the symptomatic spinal segment, which may fail to detect infection foci in other spinal regions. The prevalence and prognostic significance of multifocal spondylodiscitis remain insufficiently characterized. Materials and Methods: A retrospective single-center cohort study was conducted at the University Medical Center Mannheim, Germany. All patients with a first diagnosis of imaging-confirmed infectious spondylodiscitis treated between 2008 and 2017 were included (n = 274). Disease distribution was classified as monosegmental, multisegmental unifocal, or multifocal. The study evaluated the detection rate of multifocal disease stratified by imaging modality (whole-spine MRI vs. segmental MRI) and assessed in-hospital mortality according to disease distribution, comorbidity burden, and pathogen type. Results: Among the 139 patients who underwent whole-spine MRI, multifocal spondylodiscitis was identified in 25 (18.0%) compared with 2 out of 116 patients (1.7%) who received segmental MRI. Overall in-hospital mortality was 16.9% (46/272). Mortality was substantially higher in patients with multifocal disease (40.0%) than in those with monosegmental (13.7%) or multisegmental unifocal involvement (15.6%, p = 0.002). Increasing comorbidity burden (7.5% with no comorbidities to 27.1% with three or more; p = 0.008) and Staphylococcus aureus infection (26.2% vs. 11.0%; p = 0.010) were also significantly associated with mortality. Conclusions: Multifocal spondylodiscitis was more frequently detected with whole-spine MRI and was associated with substantially increased in-hospital mortality. These findings support consideration of a low threshold for whole-spine MRI in the primary diagnostic workup of suspected spondylodiscitis. Further prospective studies are required to confirm these findings. Full article

Background and Objectives: We aimed to determine whether gynecologic cancer–related factors are associated with postoperative clinically significant cognitive decline (CCD) after accounting for age and comorbidity using competing-risk models. Materials and Methods: We performed a retrospective cohort study of adult women undergoing index surgery for gynecologic cancer at a tertiary university hospital. CCD was defined as new clinician-documented cognitive impairment, neurology/psychiatry consultation, or initiation of cognition-targeted pharmacotherapy ≥30 days postoperatively. Competing events were all-cause death and major neurologic events/hospice. We fit Fine–Gray subdistribution hazard models adjusted for age, Charlson Comorbidity Index (CCI), cancer stage, and treatment intensity, and evaluated a prespecified age × stage interaction. Results: Among 1023 eligible patients (mean age 62.4 ± 11.8 years; 41.3% International Federation of Gynecology and Obstetrics [FIGO] stage III–IV; median CCI 3 [IQR 2–5]), CCD occurred in 98 (9.6%). The 12-month cumulative incidence of CCD was 11.2% accounting for competing risks. Advanced stage was independently associated with higher CCD risk (sHR 1.85, 95% CI 1.27–2.69; p = 0.001). A significant age × stage interaction was observed (p < 0.001), with the strongest association in patients ≥70 years (sHR 2.48, 95% CI 1.61–3.81). Perioperative factors associated with CCD included open surgery (sHR 1.54) and postoperative delirium (sHR 2.76); these findings should be interpreted as associative signals rather than validated causal treatment targets. A stratified blinded chart review of 160 patients (80 flagged-positive and 80 unflagged controls) supported the CCD definition (PPV 88.8%; sensitivity 72.1%; specificity 94.3%; NPV 91.5%). Visit-frequency adjustment confirmed robustness (advanced stage sHR 1.78; p = 0.003). Conclusions: Gynecologic cancer–related factors, particularly advanced stage, are independently associated with CCD after accounting for competing risks, and high-risk phenotypes (age ≥70, FIGO III–IV) may benefit from perioperative pathways integrating cognitive screening, delirium prevention, and neurocognitive follow-up.

Background and Objectives: FLOT is a highly effective first-line treatment for metastatic gastric cancer and offers a favorable safety profile. Clinical studies investigating the FLOT regimen have reported varying outcomes depending on the infusion duration and have highlighted possible differences in complication rates and the efficacy of neoadjuvant therapy. The choice between 24 h or 48 h infusion durations for fluorouracil can be influenced by several factors, such as the patient’s overall health status, their tolerance to treatment, and the specific treatment protocol determined by the medical team. In this study, we aimed to evaluate the effects of different infusion durations (24 and 48 h) on clinical response, toxicity, and survival in patients with gastric and gastroesophageal junction (GEJ) adenocarcinoma. Materials and Methods: This retrospective multicenter study included 113 patients with gastric or gastroesophageal junction adenocarcinoma who received neoadjuvant FLOT chemotherapy (24 h infusion: n = 28; 48 h infusion: n = 85). Propensity score matching (PSM) was performed to balance baseline characteristics, yielding a matched cohort of 90 patients. The primary endpoints were the pathologic complete response (pCR) and toxicity. Secondary endpoints included disease-free survival (DFS) and overall survival (OS). Results: Significant baseline imbalances existed (cT stage p < 0.001). After PSM, the balance improved (cT stage p = 0.009). In the matched cohort, pCR 11.1% (24 h) vs. 12.1% (48 h), p > 0.99. The median DFS was 27.4 mo (24 h) vs. NR (48 h), p = 0.847. The median OS was 32.8 mo in both, p = 0.797. Multivariate analysis (baseline variables) indicates that infusion duration is not prognostic (DFS HR = 0.77, p = 0.453; OS HR = 0.72, p = 0.328). Power was ~10% for a 1% pCR difference. Conclusions: The 24 h infusion protocol was associated with similar outcomes to the 48 h protocol after PSM adjustment. However, residual confounding persists (cT stage p = 0.009 despite PSM), and the combination of this study’s retrospective design and severe underpowering (~10%) precludes definitive conclusions. As a result, the findings are hypothesis-generating. Full article

Metabolic dysfunction-associated steatotic liver disease (MASLD) is strongly associated with metabolic abnormalities, shares pathophysiological pathways with metabolic syndrome, and has become a leading cause of chronic liver disease in industrialized nations. In the absence of approved pharmacological treatments and due to its high risk of progression to advanced fibrosis, MASLD represents a significant clinical challenge. Incretin-based therapies, originally developed for the treatment of type 2 diabetes mellitus and obesity, have recently gained attention as promising therapeutic strategies in hepatology. Among them, GLP-1 receptor agonists have shown efficacy in reducing hepatic steatosis, inflammation, and fibrosis-related biomarkers, primarily through weight loss and enhanced insulin sensitivity. Dual agonists targeting both GLP-1 and GIP receptors, such as tirzepatide, have demonstrated superior outcomes in improving hepatic and metabolic parameters. Emerging agents like cotadutide (a GLP-1/glucagon receptor agonist) and retatrutide (a GLP-1/GIP/glucagon triagonist) represent a novel therapeutic frontier, with early clinical data indicating potent hepatoprotective effects and favorable metabolic remodeling. This narrative review examines the hepatoprotective potential of incretin-based therapies, highlighting how targeted intervention on the underlying metabolic dysfunction may lead to significant improvements in MASLD. These therapies may also exert beneficial effects on fibrosis progression; however, the currently available evidence remains limited. Full article

Background and Objectives: There is limited evidence supporting the incorporation of dietary patterns into heart failure (HF) management. The Dietary Approaches to Stop Hypertension (DASH) diet is linked to cardiovascular disease prevention, but evidence correlating DASH adherence to HF risk is sparse. This study is the first prospective investigation into the relationship between the DASH diet, incident HF and its associated risk factors—hypertension and diabetes mellitus (DM)—in Australian women. Materials and Methods: Survey data (2001–2022) from the Australian Longitudinal Study on Women’s Health (ALSWH) was analysed, where DASH diet scores were calculated from food frequency questionnaire (FFQ) responses and categorised into quintiles. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between DASH adherence and incident HF. Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% CIs for secondary endpoints, hypertension and DM, and dietary exposure was modelled as a time-varying covariate. Results: 10 594 women (mean age 52.5 ± 1.45 years) participated and, at 21-year follow-up, there were 136 (1.3%) cases of HF, 2182 (20.6%) and 994 (5.7%) cases of hypertension and DM, respectively. After adjustment for covariates (including age and socioeconomic factors), no association was found between the highest DASH quintile and incident HF [OR 0.73, 95% CI: 0.37–1.43; p = 0.20]. However, adjusted HRs for hypertension and DM—0.73 (95% CI: 0.63–0.84; p < 0.001) and 0.65 (95% CI: 0.53–0.81; p < 0.001), respectively—indicated significant associations. Conclusions: In Australian women, DASH diet adherence was associated with a significantly lower risk of hypertension and DM, both of which are HF risk factors. The finding of no direct statistically significant association between the DASH diet and incident HF might reflect the small incidence of HF in our cohort. Full article

Background and Objectives: Perioperative fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) is the standard of care for resectable gastric and gastroesophageal junction adenocarcinoma; however, up to 50% of patients develop metastatic recurrence. These patients have prior exposure to platinum and taxane agents, and optimal first-line treatment in the metastatic setting remains undefined. This study aimed to characterize real-world treatment patterns and outcomes in patients progressing after perioperative FLOT, focusing on relapse timing and HER2 status. Materials and Methods: This retrospective, multicenter cohort study included 296 patients from 31 centers across Türkiye, stratified into early relapse (≤6 months, n = 114) and late relapse (>6 months, n = 182) groups. Survival analyses were performed using the Kaplan-Meier method and Cox proportional hazards regression. Primary endpoints were progression-free survival (PFS) and overall survival (OS). Results: Median PFS and OS for the entire cohort were 6 and 9 months, respectively. Early relapsers had significantly shorter median PFS (4 vs. 6 months, p = 0.029) and OS (8 vs. 12 months, p = 0.047); however, early relapse timing did not retain independent prognostic significance on multivariable analysis. No significant difference in PFS or OS was observed between cytotoxic chemotherapy regimens in either relapse group. HER2 positivity was the only independent predictor of improved PFS on multivariable Cox analysis (HR 0.48, 95% CI 0.29–0.81; p = 0.006). In the late relapse group, trastuzumab-based chemotherapy achieved a median PFS of 14 months and OS of 18 months, significantly superior to all cytotoxic regimens (PFS p = 0.007; OS p = 0.029). Conclusions: In patients progressing after perioperative FLOT, cytotoxic chemotherapy regimen selection did not demonstrate a statistically significant survival difference in this retrospective cohort, regardless of relapse timing. HER2 positivity is the dominant predictive biomarker, and trastuzumab-based therapy suggests a potential survival benefit that warrants prospective validation. Comprehensive biomarker profiling at metastatic diagnosis and prospective trials designed for this post-FLOT population are needed to establish evidence-based treatment standards. Full article

Background and Objectives: Subcortical bone cysts at the tibial attachment of the medial meniscus posterior root (MMPR) may reflect chronic degenerative changes; however, their clinical significance in medial meniscus posterior root tear (MMPRT) remains unclear. This study assessed whether bone cysts are associated with symptom duration and whether their presence influences healing status or medial meniscus extrusion (MME) after transtibial pullout repair (TPR). Materials and Methods: Seventy-four consecutive patients who underwent arthroscopic TPR for MMPRT between January 2022 and December 2024 were retrospectively reviewed. After applying exclusion criteria, 50 patients were included and divided into cyst-positive (n = 20) and cyst-negative (n = 30) groups based on preoperative MRI findings. Clinical outcomes, MME, and second-look arthroscopic healing status at 6 months postoperatively were compared between groups. Multivariable linear regression analysis was performed to identify independent predictors of postoperative MME. Results: The cyst-positive group had significantly longer symptom duration than the cyst-negative group (13.8 ± 3.0 vs. 8.8 ± 2.8 weeks, p < 0.001) and demonstrated higher grades of MMPR degeneration (p < 0.05). Complete healing was observed in 60.0% of patients in each group, and no failed healing cases were noted. Postoperative MME at 6 months was comparable between groups (3.8 ± 0.8 vs. 3.8 ± 1.0 mm). Multivariable regression analysis identified baseline MME as the strongest independent predictor of postoperative MME (β = 0.67, p < 0.001), whereas bone cyst presence was not independently associated with postoperative extrusion. Conclusions: Subcortical bone cysts at the MMPR attachment are associated with longer symptom duration and more advanced root degeneration. However, their presence was not significantly associated with healing status or postoperative MME after MMPRT repair. These findings suggest that bone cyst formation may be associated with chronic degenerative changes at the root attachment, but should not discourage surgeons from performing root repair.

Background and Objectives: This study aimed to evaluate the diagnostic performance of endoscopic ultrasound (EUS) in comparison with computed tomography (CT) and magnetic resonance imaging (MRI) in the characterization of pancreatic lesions, and to assess the concordance of imaging findings with histopathological outcomes. Materials and Methods: A total of 76 patients who underwent EUS for pancreatic lesions between April 2021 and April 2022 were retrospectively analyzed. EUS findings were compared with CT and/or MRI in terms of lesion size, localization, and morphological characteristics. Histopathological results and laboratory parameters, including serum amylase, lipase, carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA 19-9), were evaluated. Diagnostic performance metrics, including sensitivity, specificity, and accuracy, were calculated. Results: The study included 76 patients (55.3% male; mean age 59.93 ± 14.03 years). EUS demonstrated superior detection of lesions smaller than 2 cm (42.1% vs. 35.5%; p < 0.01) and a higher ability to identify solid components (17.1% vs. 9.7%; p < 0.01) compared to cross-sectional imaging. While overall sensitivity for malignancy was comparable between modalities, EUS showed higher specificity (58.33%) and diagnostic accuracy (55.26%). Pancreatic duct dilation, solid lesion morphology, larger lesion size, and elevated CA 19-9 levels were significantly associated with malignant pathology (p < 0.05). A descriptive agreement analysis revealed moderate concordance between EUS and radiological imaging in lesion size classification and morphological characterization. Conclusions: EUS demonstrates superior performance in detecting small pancreatic lesions and identifying solid components associated with malignancy. Although its sensitivity is comparable to CT and MRI, its higher specificity and diagnostic accuracy support its important role in lesion characterization. However, EUS should be considered complementary to cross-sectional imaging within a multimodal diagnostic approach. Integration of imaging findings with biochemical markers may further enhance diagnostic accuracy and clinical decision-making. Larger prospective studies with standardized protocols are warranted to validate these findings. Full article

Background and Objectives: Papillary thyroid microcarcinoma (PTMC) is generally indolent; however, a subset exhibits aggressive features, reflecting biological heterogeneity. In the era of treatment de-escalation and active surveillance, accurate risk stratification is essential. We aimed to evaluate recurrence, identify factors associated with recurrence, determine predictors of lymph node metastasis (LNM) at diagnosis, and assess management strategies at our center. Materials and Methods: This retrospective study included 302 patients with PTMC. Associations between clinicopathological variables and outcomes were evaluated using chi-square test, Spearman correlation, and univariate and multivariate logistic regression analyses. Results: The cohort included 240 females (79.5%) and 62 males (20.5%), with a median age of 47 years. Total thyroidectomy was performed in 97.7%, and radioactive iodine (RAI) in 64.2%. LNM was identified in 26 patients (8.6%). Recurrence occurred in 4 patients (1.3%), and 98.0% were alive at last follow-up. Recurrence was associated with LNM at diagnosis, higher ATA risk categories, and positive surgical margins (p < 0.005). Younger age, larger tumor size, and vascular invasion independently predicted LNM (all p < 0.05), while autoimmune thyroiditis was associated with a reduced risk (p = 0.020). Conclusions: PTMC demonstrates clinically relevant heterogeneity, particularly in patients with LNM. However, given the limited number of recurrence events, recurrence-related findings should be interpreted cautiously and considered exploratory. These findings support risk-adapted management and careful patient selection in the era of treatment de-escalation. Full article

Background and Objectives: Dysfunction of the airway epithelial barrier is increasingly recognized as an early pathogenic mechanism in allergic respiratory diseases. Although individual aeroallergens such as ragweed (RW) pollen and house dust mite (HDM) are known to impair epithelial integrity, the effects of combined exposure, more reflective of real-world conditions, remain insufficiently characterized. This study aimed to evaluate the impact of single versus combined allergen exposure on airway epithelial barrier function using a multimodal experimental approach. Materials and Methods: Differentiated normal human bronchial epithelial (NHBE) cells were exposed to RW (100 µg/mL), HDM (100 µg/mL), or a combined extract (RW + HDM; total 100 µg/mL). Barrier function under air–liquid interface conditions was assessed by transepithelial electrical resistance (TEER), while real-time cellular responses were evaluated using xCELLigence impedance monitoring. Structural alterations were examined by occludin-based immunofluorescence imaging, and transcriptional changes associated with epithelial stress and inflammation were analyzed by RT-qPCR. Results: Allergen exposure induced time- and concentration-dependent impairment of epithelial barrier function. Combined exposure resulted in the most pronounced and sustained reduction in TEER and impedance measurements. These functional changes were accompanied by disruption of tight junction organization and coordinated transcriptional modulation of genes involved in inflammatory and stress responses. Conclusions: Combined exposure to RW and HDM extracts induced more severe and persistent epithelial barrier dysfunction than individual allergens. These findings support the role of the airway epithelium as a central regulator of allergic airway disease and highlight barrier disruption as an early pathogenic event. The multimodal framework applied in this study provides an integrated platform for investigating epithelial responses to complex environmental exposures. Full article

Background and Objectives: Cardiovascular risk prediction models (RPMs) are widely used to guide statin initiation in primary prevention, yet the extent to which different models produce concordant treatment decisions in the same population remains insufficiently characterized. We compared statin eligibility across nine commonly used RPMs: SCORE2, PREVENT, PCE, ASSIGN, FRS-hCHD, AusCVDRisk, MESA, QRISK3, and RRS. Materials and Methods: We performed a cross-sectional analysis of 11,174 adults aged 40–65 years with metabolic syndrome enrolled in the Lithuanian High Cardiovascular Risk primary prevention program (LitHiR) and evaluated them at a single tertiary center during 2006–2023. Statin eligibility was determined for each RPM using guideline-mapped treatment thresholds. Pairwise agreement was assessed using Cohen’s κ, Gwet’s AC1, Positive and Negative Percent Agreement (PPA/NPA), the Jaccard index, and McNemar testing. Analyses were repeated by sex. Consensus eligibility was defined as treatment recommended by at least k of nine models. Results: Eligibility varied more than twenty-fold, from 67.39% (7530/11,174) with SCORE2 to 3.03% (339/11,174) with AusCVDRisk; intermediate estimates included PREVENT at 44.83%, QRISK3 at 39.00%, and PCE at 37.97%. Overall pairwise agreement was modest: κ ranged from 0.03 (SCORE2 vs. AusCVDRisk) to 0.67 (QRISK3 vs. ASSIGN), with a median κ of 0.38 (IQR: 0.19–0.51). Median AC1 was 0.58 (IQR 0.37–0.68). Agreement was stronger for non-eligibility than for eligibility (median NPA: 0.82 vs. median PPA: 0.53). Consensus eligibility declined from 73.5% at k = 1 to 45.1% at k = 3, 30.0% at k = 5, and 1.87% at k = 9, with the greatest sex divergence at intermediate stringency. Conclusions: In this real-world cohort with elevated cardiometabolic risk, statin eligibility was highly dependent on RPM choice and showed only modest inter-model concordance. Increasing consensus stringency rapidly reduced eligibility, indicating that RPM selection and embedded thresholds substantially influence statin treatment decisions in primary prevention.

Background and Objectives: Adolescent idiopathic scoliosis (AIS) may influence pelvic orientation and lower-limb alignment; however, data on coronal lower-limb alignment after completion of spinal treatment remain limited. This study aimed to evaluate lower-limb radiographic alignment in AIS patients after spinal treatment and to determine whether these parameters differ according to main curve location. Materials and Methods: In this retrospective study, 70 AIS patients treated surgically (n = 52) or with brace therapy (n = 18) between 2010 and 2020 were analyzed. Patients were grouped according to main curve location as thoracic (n = 28), lumbar (n = 21), or thoracolumbar (n = 21). Pre-treatment standing full-spine radiographs were used to assess Cobb angle, coronal balance, and pelvic coronal obliquity angle (PCOA). After completion of spinal treatment, full-length weight-bearing lower-limb radiographs were evaluated for femoral and tibial lengths, mechanical axis deviation (MAD), femoral neck–shaft angle (NSA), anatomical lateral distal femoral angle (aLDFA), and mechanical lateral distal femoral angle (mLDFA). Additional treatment-stratified, treatment-adjusted, and threshold-based analyses were performed. Results: PCOA, coronal balance, bilateral MAD, right aLDFA, and right mLDFA differed significantly among the three curve-location groups. The lumbar group demonstrated more negative MAD values than the thoracic group, indicating a tendency toward valgus alignment (right MAD: −5.88 ± 8.8 mm vs. 3.65 ± 7.9 mm, p = 0.004; left MAD: −3.5 ± 7.5 mm vs. 3.75 ± 7.0 mm, p = 0.005). After adjustment for treatment modality, age, and main Cobb angle, curve location remained significantly associated with right MAD, left MAD, right aLDFA, and right mLDFA. However, the proportion of patients with clinically relevant malalignment, defined as MAD exceeding ±10 mm in at least one limb, did not differ significantly among the groups. Conclusions: AIS patients show subtle but measurable differences in coronal lower-limb alignment after completion of spinal treatment. Lumbar and thoracolumbar curves are associated with greater pelvic obliquity and a tendency toward more valgus mechanical-axis alignment, whereas limb lengths and NSA remain comparable among curve-location groups. These findings appear to represent mainly radiographic or biomechanical variations rather than overt clinically relevant deformity in most patients. Full article

Background and Objectives: Minimally invasive cervical spine surgery (MIS-CSS) relies heavily on intraoperative fluoroscopic imaging, raising concerns about radiation exposure to patients and surgical staff. Unlike lumbar MIS, cervical-specific radiation exposure has not been systematically reviewed, despite distinct anatomical considerations, including proximity to the thyroid gland and lens of the eye. This review aims to quantify intraoperative radiation exposure during MIS cervical spine procedures and evaluate available dose-reduction strategies. Materials and Methods: A systematic literature search was conducted across PubMed/MEDLINE, Scopus, and Google Scholar in April 2026 following PRISMA 2020 guidelines. Studies reporting original quantitative radiation data during minimally invasive cervical spine procedures in adult patients (≥10 patients) were included. Quality was assessed using the MINORS tool and the JBI checklist. Results: Seven studies encompassing 380 patients were included. Procedures comprised ACDF (four studies), minimally invasive posterior cervical laminoforaminotomy (two studies), and CT-navigated cervical instrumentation (one study). Patient effective doses during ACDF ranged from 0.015 to 1.3 mSv, with thyroid doses of 0.194–0.290 mGy. Standalone ACDF reduced patient dose by 36–58% compared to plated ACDF (p < 0.001). Navigation-assisted posterior cervical foraminotomy achieved a median fluoroscopy time of 10 s with negligible staff exposure. Surgeon per-procedure exposure during cervical discectomy (chest 0.122 µSv, lens 3.1 µSv, hands 7.1 µSv) was approximately half that of lumbar discectomy. Conclusions: Radiation doses during individual MIS cervical procedures appear to be within occupational safety limits, though the current evidence is insufficient to establish definitive dose thresholds. Standalone implant designs and intraoperative navigation represent effective, complementary dose-reduction strategies. Standardized prospective research is needed to establish cervical-specific radiation safety benchmarks. Full article

Background and Objectives: Paramedian cervical interlaminar epidural steroid injection (CESI) is commonly used for cervical radicular pain and is considered safer than the transforaminal approach. However, its clinical effectiveness may be influenced by contrast distribution patterns, although these may not fully reflect actual drug delivery. This study aimed to evaluate the association between needle trajectory, foraminal or periradicular contrast distribution patterns, and short-term pain reduction following paramedian cervical interlaminar CESI. Materials and Methods: This single-center retrospective study included 109 patients who underwent paramedian cervical interlaminar CESI. Needle trajectory was classified as inward or outward. Contrast distribution was graded based on anteroposterior (AP) spread patterns. Pain intensity was assessed using a numeric rating scale (NRS) at baseline and 2 weeks after the procedure. Group comparisons were performed using Welch’s t-test and chi-square or Fisher’s exact test, as appropriate. Effect sizes were calculated using Cohen’s d and η². Multivariable linear regression analysis was performed adjusting for age, sex, baseline NRS, and target level. Results: The outward trajectory group demonstrated a significantly higher proportion of Grade 2 contrast spread compared to the inward group (69.8% vs. 8.9%, p < 0.001). Higher AP contrast spread grades were associated with greater pain reduction (β = 0.83, 95% CI: 0.44–1.22, p < 0.001; η² = 0.14). In addition, patients in the outward trajectory group showed greater NRS reduction than those in the inward group (2.96 vs. 1.71, mean difference: 1.25, 95% CI: 0.74–1.76, p < 0.001; Cohen’s d = 0.96). In multivariable analysis, needle trajectory remained significantly associated with pain reduction, whereas AP contrast spread grade was not independently associated. Conclusions: Needle trajectory was associated with contrast distribution patterns and short-term pain reduction following paramedian cervical interlaminar CESI. An outward-directed trajectory was associated with greater foraminal or periradicular contrast spread and greater pain reduction. These findings suggest that needle trajectory may represent a clinically relevant procedural factor influencing clinical outcomes. Full article

Background and Objectives: Benign prostatic hyperplasia (BPH) is a progressive, androgen-dependent condition driven by dihydrotestosterone (DHT). 5α-reductase inhibitors (5-ARIs), including finasteride and dutasteride, target this pathway and provide disease-modifying effects. Materials and Methods: This narrative review summarizes evidence from randomized trials, meta-analyses, and observational studies evaluating the efficacy, timing, and safety of 5-ARIs in the management of LUTS due to BPH. Results: 5-ARI therapy reduces prostate volume by 18–28% and serum PSA by approximately 50% within 6–12 months. Landmark trials (MTOPS, CombAT) demonstrate significant reductions in acute urinary retention (AUR) and BPH-related surgery (>50% RR reduction). Combination therapy with α-blockers provides superior symptom control and greater prevention of clinical progression, particularly in men with prostate volume ≥ 30–40 mL or PSA ≥ 1.5 ng/mL. Early initiation of combination therapy improves long-term outcomes, while α-blocker withdrawal may be feasible in selected patients. Adverse events are mainly sexual, with emerging data suggesting a possible association with depression. Conclusions: 5-ARIs are central to BPH management, offering sustained clinical benefits and prevention of progression. Optimal outcomes depend on appropriate patient selection, early treatment in high-risk individuals, and individualized long-term strategies. Full article

Background/Objectives: Dietary adherence to the Dietary Approaches to Stop Hypertension (DASH) pattern is associated with lower blood pressure; however, most prior studies have relied on office-based measurements and non-specific dietary assessment tools. This study examined the association between DASH diet quality, assessed by the validated DASH-Q questionnaire, and 24-h ambulatory blood pressure in treatment-naive adults referred for diagnostic ambulatory blood pressure monitoring (ABPM). Materials and Methods: This cross-sectional study enrolled 227 consecutive treatment-naive adults referred for diagnostic 24-h ABPM at a cardiology outpatient clinic. DASH diet quality was assessed using the validated Turkish version of the DASH-Q questionnaire and categorized as low (<36), moderate (36–49), or high (≥50). Hypertension was defined by ABPM-based thresholds. Multivariable linear regression was performed to identify independent predictors of 24-h mean systolic and diastolic blood pressure, and binary logistic regression was used to evaluate independent predictors of ABPM-defined hypertension, with both models adjusted for age, sex, BMI, smoking, physical activity, and self-reported discretionary salt-adding behavior. Results: DASH-Q total score was the sole statistically significant independent predictor of both 24-h mean systolic blood pressure (B = −1.068, 95% CI: −1.270 to −0.866; β = −0.589; p < 0.001) and diastolic blood pressure (B = −0.560, 95% CI: −0.706 to −0.414; β = −0.470; p < 0.001) in the adjusted models. Each one-unit higher DASH-Q score was also associated with 14.6% lower odds of ABPM-defined hypertension (OR = 0.854, 95% CI: 0.820–0.890; p < 0.001). Higher DASH-Q scores were further associated with a more favorable metabolic profile, including lower LDL cholesterol, triglycerides, glucose, and C-reactive protein levels. Conclusions: DASH diet quality was independently and inversely associated with 24-h ambulatory blood pressure and the odds of ABPM-defined hypertension in this treatment-naive population. Given the cross-sectional design and the possibility of reverse causality, these results should be interpreted as hypothesis-generating and require confirmation in prospective studies. Full article
