Background: The core management of most individuals with asthma and COPD is daily treatment with inhalers such as inhaled corticosteroids (ICS) and long-acting bronchodilators. The two main types of inhalers used are pressurized metered-dose inhalers (pMDIs) and dry powder inhalers (DPIs). Different studies have shown low adherence to inhaler treatments among subjects with asthma and COPD. In this study, we explored the differences in adherence between pMDIs and DPIs of combined ICS and long-acting β₂-agonist inhalers (ICS + LABA) in a large cohort, free from commercial biases. Methods: In this historical prospective study, we included all adult subjects with asthma and/or COPD who acquired at least one ICS + LABA inhaler between 2016 and 2019. We carried out propensity score matching and then compared the maximal number of pMDIs and DPIs purchased in any continuous 12 months during the study period. We also compared once-a-day DPIs with twice-a-day DPIs. Results: Of the 36,998 matched subjects, 5897 (15.9%) purchased pMDIs. The overall median [IQR] inhalers purchased for pMDIs and DPIs were 1 [1, 4] and 3 [1, 8], respectively; for subjects with asthma, 1 [1, 3] and 2 [1, 6]; for subjects with COPD, 1 [1, 3] and 3 [1, 10]; and for subjects with asthma–COPD overlap, 2 [1, 7] and 6 [2, 12]. For all the comparisons, p < 0.001. The once-a-day DPI group had a slight but significantly better adherence than the twice-a-day DPI group. Conclusions: For ICS + LABA therapy, the number of DPIs purchased was significantly greater than the number of pMDIs purchased, as well as the once-a-day DPI relative to the other DPIs. Overall, subjects with asthma and/or COPD had low adherence to all inhalers, with the highest adherence observed among subjects with asthma–COPD overlap. Full article

Background/Objectives: Decompressive craniectomy (DC) is commonly applied to manage refractory intracranial hypertension in severe traumatic brain injury (TBI). However, its role and benefits in pediatric populations remain uncertain. Clarifying whether DC provides measurable clinical advantages in children with severe TBI may inform treatment strategies and family counseling. Methods: We conducted a retrospective, one-to-one matched cohort study at a tertiary pediatric center (2014–2023). Fifty-three children with severe TBI who underwent DC were matched with fifty-three non-DC patients based on age, Glasgow Coma Scale score, cranial CT findings, and pupillary response at admission to ensure comparable injury severity. Demographic data, clinical features, and outcomes were collected. Primary outcomes were in-hospital mortality and Pediatric Cerebral Performance Category (PCPC) scores at discharge and 3 months. Secondary outcomes included duration of mechanical ventilation, intensive care unit (ICU) stay, and total hospital stay. Results: Mortality did not differ significantly between DC and non-DC groups (17.0% vs. 26.4%, p = 0.239). DC patients had better PCPC scores at discharge (p = 0.029). At 3 months, the between-group difference was not statistically significant but showed a near-significant trend (p = 0.057). No significant differences were observed in duration of ventilation (p = 0.100), ICU stay (p = 0.348), or hospital stay (p = 0.678). Conclusions: DC may not reduce short-term mortality in pediatric severe TBI but appears to be associated with more favorable neurological outcomes at discharge. Larger, adequately powered studies with standardized monitoring and longer follow-up are needed to clarify the durability and scope of potential benefits in this population. Full article

Background and Objectives: Minimally invasive surgery is considered the standard of care for early-stage endometrial cancer. However, the oncological safety of intrauterine manipulator (IUM) use during laparoscopic hysterectomy remains controversial. The aim of this study was to evaluate the impact of intrauterine manipulator use during laparoscopic hysterectomy on oncological outcomes in patients with clinically early-stage endometrial cancer. Materials and Methods: In this retrospective cohort study, 612 patients with FIGO 2009 stage I–III endometrial cancer who underwent staging surgery at a tertiary center between January 2010 and May 2025 were included. Clinical and pathological characteristics were compared between laparoscopy (n = 168) and laparotomy (n = 444). To reduce selection bias, propensity score matching (PSM) was performed based on age, histological subtype, and FIGO stage. Kaplan–Meier survival analysis and Cox regression modeling were utilized to evaluate disease-free survival (DFS) and overall survival (OS). Results: After matching, groups were balanced except for higher rates of para-aortic lymphadenectomy and adjuvant therapy in the laparotomy group. IUM use was not associated with increased LVSI or positive peritoneal cytology. Recurrence was more frequent after laparoscopy (10.1% vs. 6.0%, p = 0.028), with inferior 5-year DFS (87.6% vs. 97.4%, HR 5.60, p = 0.0006), while OS was similar (82.0% vs. 87.6%, p = 0.842). In multivariate Cox analysis, independent predictors of worse DFS were non-endometrioid histology (HR 3.57), FIGO stage III (HR 3.06), grade 3 tumors (HR 2.63), and laparoscopic surgery (HR 0.51). For OS, non-endometrioid histology (HR 5.12), stage III disease (HR 2.98), and grade 3 tumors (HR 4.51) were independent adverse factors, whereas surgical approach was not. Conclusions: The use of an intrauterine manipulator in laparoscopic hysterectomy for early-stage endometrial cancer was linked to worse DFS but not OS. These findings suggest caution regarding the routine use of IUMs and highlight the need for prospective randomized trials to clarify their oncological safety. Full article

Objectives: This study aimed to assess the impact of traditional Korean medicine services (TKMS) on subsequent knee surgery and opioid use in patients diagnosed with knee osteoarthritis (KOA). Methods: This retrospective cohort study used National Health Insurance Review and Assessment Service claims data from 2015 to 2017 to identify patients treated for KOA (M17) in 2016. Patients with at least two Korean medicine (KM) clinic visits within 6 weeks of the initial diagnosis formed the TKMS group, while those without visits to KM clinics formed the n group. Propensity score matching (PSM) (1:1) was applied and the incidence of knee surgery and opioid use was followed up for one year. Kaplan–Meier survival curves and Cox proportional hazards models estimated time-to-event outcomes and hazard ratios (HRs). Sensitivity analyses were performed to verify the results across varied treatment windows of 4, 8, and 10 weeks. Results: After PSM, 247,168 patients were included in the analysis for each group. The TKMS group exhibited significantly lower HRs for knee surgery (HR = 0.69, 95% CI: 0.66–0.72), opioid use (HR = 0.66, 95% CI: 0.65–0.66), and their compound events (HR = 0.66, 95% CI: 0.65–0.67) compared with the Non-TKMS group. The results remained consistent across sensitivity analyses. Conclusions: Among patients with KOA, the utilization of TKMS may significantly reduce the incidence of knee surgery and opioid use. Thus, the utilization of TKMS may be associated with a reduced need for unnecessary surgical interventions and with lower reliance on high-risk medications. Full article

Objectives: Antimicrobial resistance is a major global health threat. This study aimed to assess the impact of antimicrobial-resistant bacterial pneumonia on in-hospital mortality and length of hospital stay in Spain using a large, nationally representative cohort. Methods: A retrospective cohort study that used data from Spain’s Registry of Specialized Health Care Activity (RAE-CMBD) between 2017 and 2022. Hospitalized adults with bacterial pneumonia were included. Hospitalization episodes with bacterial antimicrobial resistance, defined according to ICD-10-CM codes for antimicrobial resistance (Z16.1, Z16.2), were analyzed versus hospitalization episodes without these codes. Multivariate logistic regression models, adjusted for potential confounders (e.g., age, comorbidity, intensive care unit admission) and sensitivity analyses (Poisson regression and propensity score matching test), were performed. Results: Of the 116,901 eligible hospitalizations, 6017 (5.15%) involved antimicrobial-resistant bacteria. Patients with antimicrobial-resistant bacterial pneumonia were older (median 75 vs. 72 years), had greater comorbidity (Elixhauser–van Walraven index: 8 vs. 5), and were more frequently admitted to the intensive care unit (22% vs. 14%). Crude in-hospital mortality was higher in the antimicrobial resistance group (18.46% vs. 10.05%, p < 0.0001), with an adjusted odds ratio of 1.47 (95% confidence interval, 1.36–1.58), p < 0.0001. Length of hospital stay was prolonged in antimicrobial resistance patients (median 14 vs. 8 days; adjusted incident rate ratio of 1.46; 95% confidence interval of 1.41 to 1.50). The most prevalent antimicrobial resistant pathogens were Staphylococcus aureus and Gram-negative bacilli (Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli). Conclusions: Antimicrobial resistance is associated with longer hospital stays and an up to 50% higher risk of mortality. Despite the implementation of control policies in place over the past decade, policymakers must strengthen AMR surveillance and ensure adequate resource allocation. Clinicians, in turn, must reinforce antimicrobial stewardship and incorporate rapid diagnostic tools to minimize the impact of antimicrobial resistance on patient outcomes. Full article

Background and Objectives: To examine the prevalence of fibromyalgia syndrome (FMS) in patients with psoriasis (PsO) and psoriatic arthritis (PsA) and its impact on treatment patterns and biologic therapy adherence. Materials and Methods: This retrospective cohort study utilized electronic health records from the Meuhedet Health Maintenance Organization in Israel between 2000 and 2020. PsO patients were matched 1:4 with controls by age, sex, and ethnicity. We assessed FMS prevalence, comorbidity burden, and treatment patterns. Cox regression and linear models evaluated the association between FMS and biologic switching and duration, adjusting for confounders. Results: Among 61,003 PsO patients and 244,012 controls, FMS prevalence was higher in PsO (3.3% vs. 2.3%, OR = 1.45, 95% CI: 1.38–1.53, p < 0.001). Among PsO patients, those with FMS were predominantly female (81.1% vs. 49.8%, p < 0.001) and had a higher prevalence of PsA (33.6% vs. 7.7%, p < 0.001). They received biologics more frequently (10.2% vs. 2.7%, p < 0.001) and were more likely to require multiple biologic lines (4.2% vs. 0.7%, p < 0.001). In PsA patients receiving biologics, FMS was associated with reduced survival on first-line therapy (6.1 vs. 10.1 years), increased switching risk (HR = 1.82, 95% CI: 1.42–2.35), and shorter treatment duration (B= −0.97 years, p = 0.001). Conclusions: In PsO patients, especially those with psoriatic arthritis, FMS is linked to greater treatment complexity and shorter biologic therapy survival, underscoring the need for tailored management strategies.

Introduction: Concussions are a growing concern in professional football due to their potential short- and long-term neurological consequences. Despite increasing global awareness, data on the epidemiology and clinical management of concussions in Portuguese football remain scarce. This preliminary exploratory study aimed to characterize the incidence, mechanisms, symptomatology, and medical response to concussions in Portugal’s Professional Football Leagues during the 2023/2024 season, based on reported cases. Methods: A retrospective observational analysis was conducted on head injuries reported by club medical teams during official matches in Liga Portugal First and Second Leagues. Collected variables included player position, time of injury, mechanism, symptoms, medical interventions and hospital referral. Results: Only six concussions were reported during official matches, with an overall incidence of 0.60 per 1000 player-hours. Most occurred in defenders, primarily due to head-to-head collisions, followed by ball impact, falls, and maxillofacial trauma. Injuries were more frequent during the final third of matches. Common symptoms included loss of consciousness, headache, and amnesia. Half of the players were referred to hospital care and underwent cranial CT scans. Among all variables analyzed, a statistically significant association was found between mechanism of injury and occurrence of amnesia (p = 0.014), with non-head-to-head impacts more frequently associated with amnesia. However, given the extremely limited sample size, this finding should be interpreted with extreme caution and requires replication in larger cohorts. Conclusions: This preliminary study suggests that defenders face a higher risk of head injuries, particularly from head-to-head impacts occurring late in matches. The prevalence of severe symptoms and the potential association between non-head-to-head impacts and amnesia highlight the need for more robust injury surveillance systems and underscore the importance of improved sideline assessment and return-to-play protocols. The findings emphasize the urgent need for comprehensive, standardized reporting mechanisms for concussions. Further research should explore long-term neurological effects and the effectiveness of preventive measures such as rule modifications, protective measures, and enhanced concussion management protocols, supported by more extensive and systematically collected data.

Background: Coronary artery disease (CAD) is common among liver transplantation (LT) candidates, yet whether pre-transplant percutaneous coronary intervention (PCI) improves post-LT outcomes remains uncertain. Methods: We conducted a single-center, Institutional Review Board-approved cohort study of adults undergoing LT from 2005 to 2025. Asymptomatic candidates with significant stenosis on invasive angiography were included; prior coronary artery bypass grafting was excluded. The primary endpoint was major adverse cardiovascular events (MACE: myocardial infarction [MI], stroke/transient ischemic attack, new systolic dysfunction, post-LT coronary revascularization, or all-cause death). Results: Among 111 patients (median age 65 years; 84% male), 66 (59%) underwent PCI and 45 (41%) were managed medically. Over a median 32 months of follow-up, 61 patients (55%) experienced MACE. Composite MACE did not differ between PCI and non-PCI groups (52% vs. 60%, p = 0.40; log-rank p = 0.59). Fine–Gray modeling showed no association of PCI with MACE; independent predictors were prior MI (HR 1.81, 95% CI 1.01–3.24) and pre-transplant dialysis (HR 2.13, 95% CI 1.07–4.24). Major bleeding occurred in 7%. Matched and era-stratified analyses were concordant. Conclusions: In asymptomatic LT candidates with angiographically severe CAD, pre-LT PCI was not associated with a lower incidence of post-LT MACE. Full article

Background: Neurodegeneration is present from the earliest stages of multiple sclerosis [MS], and oxidative stress together with mitochondrial dysfunction are key contributors to neuronal injury and disease progression. Objective: To investigate the role of the antioxidant enzyme paraoxonase 1 (PON1) and serum asymmetric dimethylarginine (ADMA) levels in MS across different disease subtypes and immunomodulatory treatments. Methods: Serum lipid levels and PON1 activity were measured and compared by disease subtype and treatment in a single-center MS cohort (N = 262; CIS = 10, RRMS = 208, PPMS = 19, SPMS = 25; 110 untreated, 152 treated) and in 91 healthy controls. ADMA levels were assessed in sera from 79 MS patients (19 untreated, 60 treated) and 31 age-matched controls. Results: Median serum paraoxonase (PON) and arylesterase (ARE) activity levels were 83.8 and 127.2 IU/L in MS patients versus 85.9 and 136.9 IU/L in controls, with no significant difference for PON (p = 0.191) but a significant reduction in ARE [p = 0.003]. PON activity differed significantly among disease subtypes (p = 0.023), with the highest levels in CIS. PON and ARE activity also varied across treatment groups (p = 0.038 and p = 0.034, respectively), with longitudinal analysis indicating a measurable effect of immunomodulatory therapy on PON activity at 10 years (p = 0.0136). Significant differences in enzyme activity were observed between untreated and interferon-treated patients (PON p = 0.0055, ARE p = 0.0001), with trends toward differences in ARE under natalizumab and fingolimod. ADMA levels were lower in MS patients than controls (p < 0.0001) and differed among treatment subgroups (natalizumab, dimethyl fumarate, glatiramer acetate, untreated RRMS). Conclusions: PON1 activity and ADMA levels differ between MS subgroups and under immunomodulatory treatments. Long-term therapy was associated with increased PON1 activity, while highly effective immunomodulators reduced ADMA levels. These changes may contribute to the treatment-related reduction in disease activity and attenuation of neurodegenerative processes in MS. Full article

Background: The impact of transfusion timing relative to endoscopy in upper gastrointestinal bleeding (UGIB) remains unclear. Aim: To assess whether transfusion performed before versus after endoscopy affects 30-day mortality in UGIB. Methods: We conducted a post hoc analysis of a multicenter cohort study including 3324 UGIB patients consecutively admitted in hospital. Propensity score matching adjusted for clinical and procedural variables. Results: Among 2017 transfused patients, 34.7% received Red Blood Cells (RBC) before endoscopy. Patients who received transfusions before endoscopy were older, had more severe comorbidities, and presented with a worse physical and hemodynamic status. This study also explored whether transfusion timing relative to endoscopy affects clinical outcomes in patients stratified by baseline hemoglobin levels. While pre-endoscopy transfusion was not significantly associated with reduced 30-day mortality in the overall population, we observed an advantage in patients transfused before the endoscopy when the Hb value was <7 g/dL. Pre-endoscopy transfusion was associated with a 6% absolute reduction in 30-day mortality (p < 0.06), with a greater benefit observed in patients with Hb < 7 g/dL (−27%) and <8 g/dL (−21%). Moreover, for this group of patients more favorable outcome was observed when the endoscopy was performed between 6 and 12 h from admission. These findings suggest that transfusion timing should be integrated into individualized UGIB management and may impact future clinical guidelines. Conclusions: In patients with severe anemia and UGIB, transfusion before endoscopy may reduce mortality. Timing to transfusion should be considered alongside hemodynamic and procedural factors in future guidelines. Full article

Background: Sodium–glucose cotransporter 2 inhibitors (SGLT2i) have shown cardioprotective effects beyond glucose control. In aortic stenosis, SGLT2 expression is upregulated in myocardium and valve tissue, contributing to inflammation, oxidative stress, thrombogenicity, and calcification. SGLT2 inhibition may counteract these mechanisms, potentially reducing bioprosthetic valve failure after transcatheter aortic valve replacement (TAVR), where the diseased native valve remains in place. Objectives: This study aimed to evaluate whether SGLT2i use is associated with improved clinical outcomes, including all-cause mortality and bioprosthetic valve failure, following TAVR. Methods: We conducted a retrospective cohort study using the TriNetX global health research network. Adults with non-rheumatic aortic stenosis who underwent TAVR were stratified by SGLT2i use. Propensity score matching (1:1) was applied to balance baseline characteristics (n = 2297 per group). Primary outcomes were all-cause mortality and bioprosthetic valve failure during follow-up. Results: Before matching, SGLT2i users had more cardiovascular comorbidities. After matching, SGLT2i use was associated with a significantly lower risk of all-cause mortality (HR: 0.83; 95% CI: 0.71–0.97; p = 0.02) and bioprosthetic valve failure (HR: 0.62; 95% CI: 0.39–0.99; p = 0.04). Conclusions: In a large real-world cohort of TAVR recipients, SGLT2i use was independently associated with reduced mortality and lower risk of bioprosthetic valve failure. These findings support a potential disease-modifying role for SGLT2 inhibitors in this high-risk population and warrant further prospective investigation. Full article

Left ventricular (LV) hypertrabeculation is increasingly recognized as a phenotype that may reflect physiological adaptation, particularly in athletes exposed to chronic overload, although its functional relevance remains uncertain. This study evaluated the prevalence of excessive trabeculation and its physiological correlation with LV remodeling. We conducted a single-center, cross-sectional study involving 320 Olympic-level athletes without cardiovascular disease. All underwent cardiac magnetic resonance (CMR). Hypertrabeculation was defined by the Petersen criteria. Athletes meeting these criteria were classified as hypertrabeculated and compared with non-hypertrabeculated matched for age, sex, and sport category. LV morphology, function, strain parameters, and hemodynamic forces (HDFs) were analyzed. Hypertrabeculation was identified in 9% of the cohort. No significant differences were observed between groups for training exposure (p = 0.262), body surface area (p = 0.762), LV volumes (end-diastolic volume indexed p = 0.397 end-systolic volume indexed p = 0.118), ejection fraction (p = 0.101), mass (p = 0.919), sphericity index (p = 0.419), myocardial wall thickness (p = 0.394), tissue characterization (T1 mapping p = 0.366, T2 mapping p = 0.833), global longitudinal strain (GLS p = 0.898), global circumferential strain (GCS p = 0.219), or HDFs. All values were within the normal range. In our cohort, LV hypertrabeculation, evaluated by CMR, was relatively common but not associated with structural or functional abnormalities, supporting its interpretation as a benign variant in asymptomatic athletes with normal cardiac function.

Background/Objectives: Atopic dermatitis (AD) is a prevalent chronic inflammatory skin disease, but its relationship with gastric cancer (GC) remains unclear. This study aimed to investigate the association between AD and GC using a nationwide Korean database. Methods: Using the Korean National Health Insurance Service-National Sample Cohort, we conducted a nested case–control study including 10,174 GC patients and 40,696 matched controls (1:4 by age, sex, income, and region). Overlap propensity score weighting was used to control for confounders. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated via logistic regression. Results: AD was significantly associated with an increased risk of GC (adjusted OR = 1.08; 95% CI: 1.01–1.15). Subgroup analyses revealed stronger associations among individuals aged ≥ 65 years (OR = 1.12), men (OR = 1.10), rural residents (OR = 1.14), and those without comorbidities (CCI = 0, OR = 1.15). Higher risks were also observed in participants with non-allergic rhinitis (OR = 1.43) or no asthma (OR = 1.12). Conclusions: AD may be associated with an increased risk of GC in the Korean population. These findings may highlight the importance of considering dermatological conditions in the context of systemic cancer risk. Full article

Background/Objectives: Stroke often results in lasting upper limb deficits. Mirror visual feedback (MVF) supports motor recovery, and electromyography-triggered electrical stimulation (ES) could enhance engagement. However, the effects in healthy older adults, age-matched to typical patient cohorts, remain insufficiently understood. We tested MVF and MVF + ES using functional near-infrared spectroscopy. Methods: Seventeen right-handed older adults performed left-wrist flexion under three visual conditions: circle fixation, viewing the right hand at rest, and mirror viewing, with/without electrical stimulation to the right-wrist flexors time-locked to left-forearm electromyography. Oxygenated hemoglobin (oxy-Hb) was recorded over the bilateral inferior frontal gyrus (IFG), precentral gyrus (PrG), postcentral gyrus (PoG), supramarginal gyrus (SMG), superior parietal lobule (SPL), and supplementary motor area. Effects were assessed with linear mixed-effects models (stimulation × visual condition); pairwise comparisons of estimated marginal means used Fisher’s least significant difference. Left-forearm electromyography verified comparable effort across conditions. Results: Linear mixed-effects models revealed left-lateralized increases in oxy-Hb, most prominently under mirror viewing with stimulation. Post hoc tests showed high oxy-Hb in the left IFG, PrG, PoG, SMG, and SMA. The left EMG did not differ. Conclusions: In healthy older adults, MVF paired with EMG-triggered ES enhances frontoparietal–motor engagement beyond MVF alone, with recruitment shaped by visuo–proprioceptive congruence. These findings support mechanistic plausibility and motivate dose–response optimization and patient-focused trials testing behavioral transfer in stroke. Full article

Background/Objectives: Joint arthroplasty revision and comorbidities are considered two increased risk factors for periprosthetic joint infection (PJI), a complication that may lead to prolonged hospital stay, continued antibiotic therapy, and serious consequences, including amputation and, in extreme cases, death of the patient. DAC^® is an absorbable barrier in the form of a gel that, when applied as a coating, protects implants from bacterial colonization. The aim of this case–control study was to explore whether the device could decrease the risk of PJI in a cohort of patients who underwent arthroplasty revision and were affected by comorbidities. Methods: We carried out a retrospective 1:1-matched case–control investigation in 96 patients who underwent arthroplasty revision between January 2023 and December 2024; these patients had at least 6 months of follow-up, had comorbidities, and were treated with DAC^® gel. The control group consisted of 96 subjects who received standard of care. Demographics, comorbidities, type of arthroplasty, adverse event onset, and incidence of PJI were recorded for all patients. Results: No significant differences in relevant demographics, type of arthroplasty revision, or number or type of comorbidities, except for smoking, were observed between the two groups. At 6-month follow-up, no PJIs were recorded in the DAC^® treatment group, whereas five (5.2%) PJIs were observed in the control group (p = 0.0235). No adverse event or impairment of implant osseointegration related to the use of DAC^® was observed. Conclusions: The DAC^® bioabsorbable hydrogel acts as a physical barrier when applied over an arthroplasty revision implant, protecting it from bacterial adhesion and preventing biofilm formation.
