Background/Objectives: Pauls Stradins Clinical University Hospital in Riga, Latvia, introduced an ECMO program in 2008. Since the program's start, countless patients have had their lives saved by this necessary technology. Our goal was to review the ECMO program results and gain insight into the organization's operations. We wanted not only to assess the program's efficiency in terms of time, but also to visualize patient outcomes at least a month after decannulation from ECMO and discharge from the hospital. Methods: A retrospective observational study was performed using hospital patient data files from October 2024 to October 2025. The selected patient group was those who had suffered an in-hospital cardiac arrest and successfully had ECMO inserted; this criterion fit fifteen patients. Data were collected on multiple factors, including from collapse to flow time, the number of days spent in the ICU, and post-ECMO complications. Afterwards, the data were analyzed to understand the program's and patients' outcomes. Results: Of the fifteen patients analyzed, seven did not survive to hospital discharge. The statistically significant quantitative results were the first lactate levels after ECMO cannulation and the first troponin levels after cardiac arrest. In terms of qualitative results, CHF, survival to ECMO decannulation, cannulation failure, and survival to ICU discharge were statistically significant. Conclusions: The ECMO program at Pauls Stradins Clinical University Hospital provides patients with a necessary technology after an intra-hospital cardiac arrest. This study highlights data about these patients and their outcomes, as well as areas for improvement within the hospital's ECMO/ECPR program.

Background/Objective: The risk of bleeding is part of blood flow pathophysiology in diabetes mellitus (DM), and there may be potential for the relationship between blood cell indices and estimated whole blood viscosity (eWBV) in DM. However, red blood cell (RBC) indices, platelet ratios, and lymphocyte ratios have been part of routine haematology tests in clinical medicine including diabetes management. This study investigated two research questions. Firstly, how does eWBV correlate with RBC indices, platelet ratios, and lymphocyte ratios? Secondly, which parameters of RBC in routine full blood count (FBC) correlate more with glycated haemoglobin (HbA1c) changes? Methods: This was a laboratory-based clinical observational cohort study using secondary data from ongoing research. Data collected included FBC and biochemistry (HbA1c and serum protein level). Dependent variables were platelet and lymphocyte ratios as well as eWBV. Results: Averages for all parameters in the cross-sectional data were within normal range, except high HbA1c (7.67%) and marginally high monocyte-to-lymphocyte ratio. In the periodic cohort analysis, only RBC distribution width showed a significant difference (p < 0.04) between cohort groups, but least correlated with HbA1c changes. Further analysis for correlations among change scores showed that RBC had the strongest positive linearity for HbA1c (r = 0.30) and among the top three for eWBV (r = 0.54), while mean cell volume (MCV) has the strongest inverse for HbA1c (r = -0.47). Conclusions: The ongoing clinical use of RBC variables is superior to profiles of platelet and/or lymphocyte ratios in assessing the potential risk of bleeding (i.e., hypo-viscosity) in diabetes.

Background/Objectives: The aim of our study was to evaluate the transverse stiffness of selected soft tissues in the knee joint region on the previously injured and uninjured sides of female handball players and non-athlete women, in the lying and standing positions, and to investigate the relationship between stiffness, age, sporting practice, and clinical assessments of the knees. Methods: A total of 25 young female handball players (the SPORT group) and 27 healthy non-athletic individuals (the CONTROL group) were examined. The MyotonPRO device was used to measure the stiffness of the patellar tendon (PT), rectus femoris (RF), and biceps femoris (BF) muscles on both sides and in both positions. The function of the knee joints was clinically assessed using the Knee Outcome Survey-Sports Activities Scale and the Lysholm Knee Scoring Scale. Results: ANOVA indicated a significant effect of group (p < 0.003) on the PT's stiffness, and a significant effect of position (p < 0.0001) on the PT, RF, and BF muscle stiffness. The SPORT group demonstrated significantly higher PT transverse stiffness when lying down (p < 0.01), but not when sitting up (p > 0.05), compared to the CONTROL group. Significant negative correlations were found between PT stiffness and both clinical scales in the SPORT group (rho from -0.39 to -0.71, p < 0.05). Conclusions: In female handball players, only the patellar tendon transverse stiffness was higher than in the control group. While this higher stiffness could indicate an adaptive rebuilding process, it was negatively correlated with the clinical assessment of joint function, meaning poorer knee joint function.

Background: Mucosal malignant melanoma (MMM) is a rare and aggressive malignancy with a dismal prognosis. While the Systemic Immune-Inflammation Index (SII) has emerged as a prognostic marker in various solid tumors, its specific value in MMM remains undefined. This study investigated the association between pretreatment SII and overall survival (OS) in patients with MMM. Methods: We retrospectively analyzed 106 adults with histologically confirmed MMM treated at six oncology centers in Turkey between 2005 and 2025. The baseline SII was calculated as platelet × neutrophil/lymphocyte counts obtained before definitive treatment. A receiver operating characteristic (ROC) analysis identified an optimal SII cutoff of 776 for overall survival (OS), defining low (<776) and high (≥776) SII groups. Results: Gastrointestinal and head and neck mucosa were the most frequent primary sites, and one-third of patients presented with metastatic disease. The median OS for the entire cohort was 23.3 months. Patients with a high versus low SII had a shorter OS (16.2 vs. 35.2 months; HR 2.71, 95% CI 1.67-4.40; p < 0.001). In multivariable analysis, a high SII (HR 1.88, 95% CI 1.12-3.14; p = 0.016), gastrointestinal primary site (HR 1.99, 95% CI 1.23-3.23; p = 0.005), and metastatic disease at diagnosis (HR 4.01, 95% CI 2.32-6.94; p < 0.001) independently predicted a worse OS. Conclusions: The SII is a novel, independent prognostic biomarker in MMM. Elevated pretreatment SII correlates with aggressive clinicopathologic features and inferior survival. As a readily accessible and cost-effective marker, SII may facilitate improved risk stratification in routine clinical practice for MMM patients.

Background: Macrocytosis commonly develops during imatinib therapy, but its relationship with cytogenetic and molecular outcomes in chronic myeloid leukemia (CML) remains unclear. We investigated whether increases in mean corpuscular volume (MCV) during imatinib treatment are associated with response depth and treatment persistence. Methods: In this retrospective study, we analyzed 101 adults with chronic-phase CML treated with a stable imatinib dose of 400 mg/day for at least 12 months. Patients with conditions that could confound MCV (hydroxyurea exposure, megaloblastic anemia, hypothyroidism, chronic liver disease, alcoholism) were excluded. Complete cytogenetic response (CCyR) and major molecular response (MMR) were assessed by conventional karyotyping and the BCR-ABL1 International Scale, respectively. Increased MCV was defined as MCV > 100 fL after six months of therapy, persisting thereafter. Associations between MCV dynamics, response, and switching to second-generation tyrosine kinase inhibitors were evaluated. Results: Twenty patients (20%) developed increased MCV. Overall, 86 patients (85%) achieved CCyR and 70 (69%) achieved MMR. All patients with increased MCV attained CCyR, compared with 66 of 81 (81%) without MCV elevation (p = 0.037), while MMR rates were 90% versus 64% (p = 0.030). During a median follow-up of 69 months, treatment modification was required in 1 of 20 (5%) patients with increased MCV versus 25 of 81 (31%) in the non-increased group (p = 0.018). Conclusions: MCV elevation during imatinib therapy is associated with deeper molecular response and reduced need for treatment modification. MCV dynamics may serve as an inexpensive pharmacodynamic marker to support risk assessment and guide monitoring in chronic-phase CML.

Background: Long-term cognitive impairment is common among ICU patients who required invasive mechanical ventilation (IMV). Its etiology is likely multifactorial. This preregistered study examined the association between the duration of IMV and cognitive function post-ICU, as well as the moderating effects of age and cognitive reserve. Methods: A secondary analysis was conducted using data from a published study of COVID-19 ICU survivors. One year after discharge, participants underwent a neuropsychological assessment. Linear regression models were used to evaluate associations between the variables. Results: Among patients who received IMV via endotracheal intubation, ventilation duration was not significantly associated with cognitive performance. In contrast, among tracheostomized patients, longer IMV duration was associated with better cognitive outcomes (Cohen's f² = 0.21). Age had a small negative main effect; in combination with IMV duration, f² increased to 0.31. Cognitive reserve showed a strong positive association with cognitive outcome; in combination with IMV duration, f² increased to 0.67. The interaction terms were negligible in both cases. Conclusions: We hypothesize that, compared to endotracheal intubation, IMV via tracheostoma may not only reduce the need for sedation, but also provide a more efficient respiratory support, therefore contributing to positive cognitive outcomes. However, IMV via tracheostomy still represents a form of positive pressure ventilation (PPV), which carries risks, such as ventilator-induced lung injury and reduced cardiac output and brain perfusion. These concerns about PPV, combined with our findings, indicate that alternative, non-invasive modes, such as negative pressure ventilation (NPV), warrant evaluation in future trials.

Coronary artery disease (CAD) remains the leading cause of cardiovascular morbidity and mortality worldwide, with plaque composition and morphology being as key determinants of disease progression and clinical outcomes. Accurate plaque characterization is essential for risk stratification and therapeutic decision-making, yet conventional image interpretation is limited by inter-observer variability and time-intensive workflows. Artificial intelligence (AI) models have emerged as a transformative tool for automated coronary plaque analysis across multiple imaging modalities. AI-driven models demonstrate high diagnostic accuracy for plaque detection, segmentation, quantification, and vulnerability assessment. Integration of AI-derived imaging biomarkers with clinical risk scores can further enhance prediction of major adverse cardiovascular events and supports personalized management. These advances position AI-enhanced imaging as a powerful adjunct for both invasive and non-invasive evaluation of CAD. Despite its promise, important barriers to widespread clinical adoption remain, including data heterogeneity, algorithmic bias, limited model transparency, insufficient prospective validation, regulatory challenges, and incomplete integration into clinical workflows. Addressing these challenges will be essential to ensure safe, generalizable, and cost-effective implementation of AI in routine cardiovascular care.

Background: Complications after proximal humerus osteosynthesis are not uncommon. The aim of this study was to compare the outcomes of osteosynthesis using PHILOS with fresh-frozen femoral head allograft augmentation and without it, and to assess the influence of risk factors and their impact on the occurrence of postoperative complications. Methods: This retrospective study evaluates the radiological outcomes and complications of treating proximal humerus fractures (Neer III-IV) in 116 patients over 50 years of age treated between 2017 and 2021. Results: Osteosynthesis without allograft was performed in 84 patients and with allograft in 32 patients. In total, 42 patients (36%) had a three-part fracture and 74 (64%) had a four-part fracture. The Deltoid Tuberosity Index was comparable between the groups (1.59 ± 0.25 vs. 1.50 ± 0.26; p = 0.802). The average duration of surgery was 101.3 ± 21.3 min with allograft and 86.0 ± 31.9 min without allograft (p = 0.004). AVN was verified in four patients (3.5%), head collapse in nine (8%), cut-out in six (5%), reoperation in eight (7%), infection in three (2.5%), and pseudoarthrosis in one (1%) case. Conclusions: An allograft augmentation improves construct stability, but cannot compensate for inadequate surgical technique. None of the risk factors significantly influenced the development of AVN and pseudoarthrosis. The greater tubercle comminution (p = 0.005), calcar loss (p = 0.020, p = 0.112), allograft augmentation (p < 0.001), and medial hinge restoration (p = 0.012, p = 0.002) were significant risk factors associated with HC and screw cut-out, respectively. The greater tubercle redislocation was influenced by its comminution, calcar loss, and the use of allograft augmentation. HFZ and DTI had no significant impact on surgery results or complications.

Background: Hyaluronic acid (HA) injections have become a cornerstone of minimally invasive aesthetic medicine. While the demand for these procedures continues to grow globally, large-scale longitudinal analyses of patient demographics and specific injection site trends remain limited, particularly in Asian populations. Existing data in Japan are largely confined to aggregate procedure numbers. This study aimed to elucidate the transition in patient demographics and site-specific treatment trends using a nationwide big-data approach. Methods: This retrospective study analyzed 299,413 treatment sessions (417,590 injection sites) from patients who underwent facial HA injections at 110 clinics across Japan between October 2020 and December 2024. Data were analyzed by year, patient age, and injection site to evaluate demographic shifts and treatment patterns. Results: The annual number of treatment sessions increased steadily during the study period. A significant demographic shift was observed: while patients in their 20s were predominant in 2020-2022, the proportion of patients aged ≥ 40 years increased markedly from 2023 onward, accounting for more than half of all cases (63.7% in 2024). Treatment preferences varied distinctly by age; younger patients favored localized contouring (e.g., pretarsal fullness, chin), whereas older patients required multi-site rejuvenation. By 2024, the orbital rim became the most frequently treated site (22.6%). Statistical analysis confirmed that age was a significant predictor for multi-site treatments (p < 0.001). Conclusions: This large-scale analysis reveals a clear transition in the Japanese aesthetic market from contour enhancement in younger demographics to anatomy-based rejuvenation in middle-aged and older populations.

Background/Objectives: Cellulite is a common aesthetic condition in women, traditionally assessed using visual inspection and palpation-based scales that are inherently subjective. Therefore, image-based methods that may support standardized severity grading are of growing interest. To evaluate infrared thermography as an imaging-based method for grading cellulite severity and to perform methodological validation of a newly developed thermographic classification scale by comparing it with clinical palpation and anthropometric parameters. Methods: This retrospective, non-interventional study analyzed anonymized clinical and thermographic data from 81 women with clinically assessed cellulite. Cellulite severity was evaluated using the Nürnberger-Müller palpation scale and a newly developed five-point thermographic scale based on skin surface temperature differentials and histogram pattern analysis. The associations between the assessment methods were evaluated using ordinal statistical measures, and agreement was assessed using weighted Cohen's kappa statistics. Results: Thermographic grading demonstrated high agreement with palpation-based assessment, with a percentage agreement of 93.8% and an almost perfect agreement based on weighted Cohen's κ. A strong ordinal association was observed between the methods. Thermography consistently classified a subset of cases as one grade higher compared with palpation. No statistically significant associations were observed between thermographic grade and body mass index or waist-to-hip ratio. Conclusions: Infrared thermography enables image-based grading of cellulite severity and shows a strong concordance with established palpation scales. The proposed thermographic classification provides preliminary methodological validation of an imaging-based grading approach. Further multicenter studies involving multiple assessors and diverse populations are required to assess reproducibility, specificity, and potential clinical applicability.
