Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD) prevalence data in Türkiye is limited. We aimed to determine the nationwide prevalence of MASLD and advanced hepatic fibrosis risk in subjects with cardiometabolic risk factors (CMRF). Despite recent international consensus redefining fatty liver disease terminology, no nationwide MASLD study has been reported in Türkiye. Methods: This cross-sectional study included 14,371 adults with ≥1 CMRF from 44 centers across 31 cities. MASLD was diagnosed using liver ultrasonography plus cardiometabolic criteria. Advanced fibrosis risk was assessed by fibrosis-4 (FIB-4) score (≥1.3 for ≤65 years; ≥2.0 for >65 years). Logistic regression was used to identify independent predictors of high FIB-4. Results: A total of 61.4% of participants were women, the mean age was 51.3 ± 14.4 years, and the mean BMI was 31.4 ± 6.0 kg/m². MASLD prevalence was 75.7% (n = 10,873), rising with the number of CMRFs (56.5% with one factor vs. 83.4% with all). The prevalence of high FIB-4 scores was 12.0% overall, being lower in MASLD patients than non-MASLD patients (11.2% vs. 14.4%, p < 0.001). FIB-4 scores decreased with increasing BMI (28.1% underweight vs. 8.7% class III obesity). Male sex, T2DM, and hypertension independently predicted high FIB-4 scores, while smoking, higher BMI, and MASLD were inversely associated. Conclusions: Three-quarters of Turkish adults with CMRF have MASLD. Standard FIB-4 thresholds may underestimate fibrosis risk in obese and smoking populations, underscoring the need for adjusted cut-offs or alternative tools. This study is the first to provide nationwide MASLD prevalence data in Türkiye.

Background: Although the cure rates of classical Hodgkin Lymphoma (cHL) are as high as 90% using the current treatment protocols, the prognosis is poor for primary refractory patients. Thus, a biomarker that can predict patients with early progression at the time of diagnosis is an unmet clinical need. Endothelial activation and stress index (EASIX) and its variant modified EASIX (mEASIX) is a scoring system currently used for the prediction of prognosis in hematologic malignancies. This study aimed to investigate the prognostic value of the mEASIX score in newly diagnosed cHL patients. Methods: Data from 206 patients who underwent positron emission tomography (PET)-guided doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) therapy for cHL between January 2007 and November 2023 were retrospectively analyzed. The prognostic value of the mEASIX score was evaluated using the receiver operating characteristic (ROC) analysis, Cox regression analysis, and the Kaplan–Meier method, and then compared with standard risk assessment methods. Results: The median age at diagnosis was 33 years, and the rate of patients in the advanced stage was 67%. ROC analysis determined an optimal mEASIX score cut-off of 17.28, categorizing patients into mEASIX^high (47%) and mEASIX^low (53%) groups. The 5-year progression-free survival (PFS) (60% vs. 84.3%) and overall survival (OS) (79.6% vs. 95.8%) were significantly lower in the mEASIX^high group (p < 0.001). Additionally, multivariate analysis showed that the independent variables affecting PFS included the nodular sclerosing subtype (HR: 0.4), bone marrow involvement (HR: 2.6), and elevated mEASIX (HR: 3.1). Independent variables, which had an effect on OS included elevated mEASIX (HR:3.8) and higher IPS-3 scores (HR:1.9). Furthermore, a higher mEASIX score (≥17.28) was identified as an independent variable indicating primary refractory disease (OR: 6.5). Conclusions: mEASIX is a powerful and easy-to-access marker for the detection of primary refractory disease and prognosis in newly diagnosed cHL cases.

Background/Objectives: The objective of this study was to evaluate the diagnostic accuracy of the lactate dehydrogenase-to-albumin ratio (LAR) in adult-onset Still’s disease (AOSD) and compare it with other inflammatory indices, using patients with fever of unknown origin (FUO) as a control group due to their overlapping clinical features with AOSD. The study also compared LAR’s diagnostic performance with other inflammatory indices like the serum immune-inflammatory index (SII), ferritin/erythrocyte sedimentation rate (FER), CRP/albumin ratio (CAR), platelet/lymphocyte ratio (PLR), and neutrophil/lymphocyte ratio (NLR), as well as its combinations with FER, PLR, and ferritin (LAR + FER, LAR + PLR, LAR + ferritin). Methods: A retrospective evaluation was conducted on 70 patients with fever of unknown cause and 78 patients with AOSD, admitted between January 2000 and December 2023 in a tertiary care hospital. Demographic, clinical, and laboratory characteristics were compared between the groups. ROC analysis provided cutoff values, sensitivity, and specificity for each inflammatory index. Results: ROC analysis showed significant p-values (p < 0.05) for indices other than LAR (p = 0.090) LAR + PLR (p = 0.806), and PLR (p = 0.634) in diagnosing AOSD. The highest specificity was found in LAR + ferritin (92.90%), and the highest sensitivity in CAR (100.0%). NLR, SII, FER, and LAR + FER were the indices with both sensitivity and specificity above 50%. LAR had a sensitivity of 76.90% and a specificity of 48.60%. The cutoff values were 3978.0 µg/L for ferritin and 70.98 for LAR. Significant statistical differences between AOSD and non-AOSD groups were observed for all indices except CAR (p = 0.133). Conclusions: LAR can differentiate AOSD patients from FUO, but its specificity is lower than most other indices. The diagnostic utility of these indices in clinical practice remains controversial.

Tyrosine kinase inhibitors (TKIs) are crucial for improving the survival rates of individuals with metastatic thyroid cancer. Moreover, systemic inflammation and malnutrition are known to negatively affect metastatic thyroid cancer prognosis. Evaluating nutritional status at the start of treatment can improve survival rates. Purpose: This study investigated the correlation between the hemoglobin, albumin, lymphocyte count, and platelet (HALP) score and prognosis of patients with metastatic thyroid cancer undergoing first-line TKI therapy. Methods: We retrospectively analyzed data from 44 patients between January 2010 and June 2024. The primary outcomes evaluated in the study were time to treatment failure (TTF) and overall survival (OS); HALP scores were categorized as low (≤29.21) and high (>29.21) based on receiver operating characteristic analysis. Results: The 1-year survival rate was significantly lower in the low HALP score group compared to the high HALP score group (50% vs. 96.3%). Multivariate Cox regression analysis revealed that low HALP scores, elevated leukocyte counts, and lymphopenia were independent predictors of shorter TTF (HR = 0.272, p = 0.011) and OS (HR = 0.208, p = 0.028). Conclusions: The results obtained in the present study demonstrate that the HALP score has prognostic significance for patients with metastatic thyroid cancer who are undergoing first-line TKI treatment. In metastatic thyroid cancer patients, interventions focused on improving nutritional status at the start, during initiation, and throughout the TKI treatment may enhance treatment effectiveness. However, further prospective studies involving larger patient cohorts are necessary to validate our results.

Despite advancements in diagnostic modalities, delineating the etiology of fever of unknown origin (FUO) remains a significant challenge for clinicians. Notably, cases with hematological malignancies often have a poor prognosis due to delayed diagnosis. This study investigated the potential of readily obtainable laboratory markers to differentiate hematological causes from other etiologies during the early stages of FUO. A retrospective analysis was conducted on the medical records of 100 patients who fulfilled the modified FUO criteria between January 2010 and April 2023. Hematological etiologies were identified in 26 of the 100 patients. Peripheral blood neutrophil, lymphocyte, platelet counts, and the systemic immune inflammation (SII) index, were significantly lower in the hematological group compared to the non-hematological group. Conversely, serum ferritin levels were demonstrably higher in the hematological group. ROC analysis identified a neutrophil-to-ferritin ratio (NFR) cutoff value of < 8.53 as optimal for predicting hematological etiology. Subsequent multivariate analysis demonstrated that the NFR was the sole independent predictor of hematological etiology (p = 0.013).This study proposes a novel approach for early diagnosis of a potentially life-threatening subset of FUO patients. The NFR presents as an inexpensive and readily available marker for predicting hematological etiology in FUO cases.

Background/Objectives: Early death (ED) remains the primary barrier to long-term survival in acute promyelocytic leukemia (APL). Since current risk stratification models rely solely on static baseline parameters, they fail to capture the high biological volatility during the induction phase. We aimed to evaluate the prognostic value of the dynamic evolution of the endothelial activation and stress index (EASIX). Materials and Methods: This multicenter, retrospective study analyzed 131 newly diagnosed adult APL patients treated with the AIDA protocol. EASIX scores were calculated at admission (D0) and day 7 (D7). ROC, landmark, multivariable logistic and Cox regression analyses were performed to assess the impact of dynamic endothelial changes (ΔEASIX) on mortality and survival. Results: The ED rate was 25.2%. While baseline EASIX successfully predicted very early death ( 0.35) was an independent predictor of early mortality (OR: 12.41, p = 0.007), inferior EFS (HR: 5.70, p = 0.004), and poor OS (HR: 3.69, p = 0.023). Landmark analysis stratified by the kinetic trajectory of ∆EASIX confirmed that patients above the optimal cut-off had significantly inferior 3-year EFS (56.3% vs. 77.8%, p = 0.041) and OS (59.5% vs. 78.0%, p = 0.026). Conclusions: To our knowledge, this is the first study to establish EASIX as a dynamic prognostic marker in APL. Our findings indicate that the “kinetic trajectory” of endothelial stress is a more accurate predictor of survival than static baseline assessment alone. While dynamic EASIX monitoring offers a valuable tool for real-time risk reclassification, these results require validation through prospective studies.
