Background: The role of severity and duration of inflammatory findings on the development of persistent hypothyroidism and anemia has not been clarified in subacute thyroiditis (SAT). Methods: Demographic data and laboratory parameters of patients with SAT were analyzed retrospectively. Results: Permanent hypothyroidism was observed in 28.1% of patients. Baseline elevated erythrocyte sedimentation rate as defined >74.5 mm/h was found to be associated with permanent hypothyroidism, but the duration of inflammation was not different between the recovered and hypothyroid patients. Baseline hemoglobin values improved without specific therapy in 3.5 months. Conclusion: The initial severity but not the duration of inflammation increases the risk for the development of permanent thyroid dysfunction, and anemia improves with the resolution of inflammation.

Objective: To assess the relationship between LRG1 and CD4⁺ T cells, cognitive impairment and neurological function in acute ischemic stroke (AIS). Methods: Plasma LRG1 was detected by ELISA in 175 patients with AIS at baseline, day (D) 1, D7, month (M) 1 and M3. Results: LRG1 was negatively related to Th2 and Treg cells and positively linked to Th17 (all p < 0.05). LRG1 increased from baseline to D1, then decreased until M3 (p < 0.001). LRG1 at each assessment point was increased in patients with cognitive impairment or poor neurological function at M3 versus those without (all p < 0.05). Conclusion: LRG1 is linked to decreased Th2 and Tregs, increased Th17, cognitive impairment and nonideal neurological function recovery in patients with AIS.

Objective: We aimed to explore the clinical value of MDS1 and EVI1 complex locus (MECOM) in lung adenocarcinoma (LUAD). Methods: Bioinformatics and experimental validation confirmed MECOM expression levels in LUAD. The value of MECOM was analyzed by receiver operating characteristic (ROC) curve and Cox regression analysis. Results: Serum MECOM levels were lower in LUAD and correlated with gender, TNM stage, tumor size, lymph node metastasis and distant metastasis. The ROC curve showed that the area under the curve of MECOM was 0.804 for LUAD and, of note, could reach 0.889 for advanced LUAD; specificity was up to 90%. Conclusion: MECOM may contribute to independently identifying LUAD patients, particularly in advanced stages.

Aim: Recurrence of hepatocellular carcinoma (HCC) after ultrasound-guided microwave ablation (UGMWA) was a critical issue. Therefore, it is significant to identify the role of hypoxia-inducible factor 1 α (HIF-1α), insulin-like growth factor-1 (IGF-1) and IGF binding protein-3 (IGFBP-3) in recurrence.Materials & methods: HCC patients receiving UGMWA were divided into recurrence and no-recurrence groups. The preoperative and postoperative risk factors were compared between these two groups.Results: Preoperative and postoperative serum levels of HIF-1α, IGF-1 and IGFBP-3 were closely associated with the recurrence of HCC. Serum HIF-1α level was increased, while serum levels of IGF-1 and IGFBP-3 were decreased in HCC patients with recurrence.Conclusion: HIF-1α, IGF-1 and IGFBP-3 were associated with and predicted the recurrence of HCC after UGMWA, respectively or in combination.

Aim: To identify the predictive role of triglyceride-glucose (TyG) index in pulmonary hypertension (PH) in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) treatment.Methods: Blood biomarkers have been measured at the cross-section of entrance. The baseline and followed-up echocardiography have been performed at both cross-sections.Results: The incidence of PH was 8.91%. The baseline myoglobin (MYO), was significantly higher among PH patients (p < 0.001). In the univariate regression, body mass index (BMI p = 0.020), left atria end-diastolic internal diameter (LAD, p = 0.083), creatinine (Cr, p = 0.005), triglyceride (TG, p < 0.001), high-density lipoprotein cholesterol (HDL-C, p = 0.056) and TyG index (p = 0.002) were potential predictors for PH. Finally, the adjusted COX regression indicated that BMI (p = 0.001), LAD (p = 0.030), Cr(p = 0.005) and TyG index (p = 0.002) were independent predictors of the onset of PH.Conclusion: Baseline TyG index, BMI, LAD, Cr level were independent predictors for PH in CAD patients after PCI treatment.

Aim: We aimed to investigate whether there is a correlation between AT and pleural effusion in PE patients.Materials & methods: We retrospectively enrolled 325 patients aged 66.26 ± 14.86 years with acute PE in 256-computed tomography pulmonary angiography (CTPA) from 2015 to 2022 and recorded radiographic, clinical and biomarker data, the patients were divided into two groups, PE with pleural effusion group (178 patients) and PE without pleural effusion group (147 patients), odds ratios (OR) were estimated for AT of pleural effusion in PE.Results: A lower AT had a significantly increased risk of pleural effusion (adjusted OR: 2.009, 95% CI: 1.225-3.295).Conclusion: AT are reduced in PE patients with pleural effusion and are associated with the risk of pleural effusion.

Aim: To examine whether there is any difference in the levels of salivary melatonin between bruxism and nonbruxism groups and to compare the stress and anxiety levels between the two groups.Materials & methods: Patients meeting the probable bruxism criteria according to the International Consensus on the Assessment of Bruxism Criteria were included in the bruxism group. The salivary melatonin concentrations of both groups were measured using an ELISA kit. To determine the relationship between stress and bruxism, the State-Trait Anxiety Inventory (STAI) test was used.Results: The bruxism group had a significantly lower night-time salivary melatonin level than the control group (p < 0.05). No significant difference was determined between the bruxism group and the control group in respect of the STAI-T scores (p > 0.05).Conclusion: The study findings revealed a strong relationship between a low melatonin level and bruxism.

Aim: The aim of the study is to evaluate whether C-reactive protein to albumin ratio (CAR), lactate dehydrogenase to albumin ratio (LAR), ferritin to erythrocyte sedimentation rate ratio (FER), systemic immune-inflammation index (SII), prognostic nutritional index (PNI) indices and ferritin level can predict organ involvement in adult-onset Still's disease (AOSD) patients.Methods: This study was planned as a cross-sectional study. Univariate and multivariate logistic regression analyses were performed to evaluate the usefulness of ferritin level and inflammatory indices in defining organ involvement.Results: Sixty-one patients diagnosed with AOSD were included in this study. Multivariate logistic regression analyzes showed that LAR (OR 1.028, 95% CI: 1.011-1.044) (p = 0.001) index predicted lymphadenopathy involvement, CAR (OR 1.249, 95% CI: 1.087-1.435) (p = 0.002) index predicted hepatomegaly involvement, ferritin level (OR 1.004, 95% CI: 1.001-1.008) (p = 0.007) predicted splenomegaly involvement, FER (OR 1.085, 95% CI: 1.012-1.164) (p = 0.021) and PNI (OR 0.271, 95% CI: 1.132-0.553) (p < 0.001) index predicted the occurrence of serositis.Conclusion: This study showed that ferritin level, CAR, FER, PNI and LAR markers may predict organ involvement at diagnosis in AOSD patients.

Objective: This study aimed to evaluate the predictive value of IL-6 for stroke recurrence in acute ischemic stroke.Methods: Patients who were admitted within 48 h of onset were included. At 3-month, stroke recurrence was assessed. IL-6 levels were measured in serum samples taken upon admission.Results: Out of the 305 patients, 47 (15.4%) experienced a stroke recurrence. The risk of stroke recurrence increased by 8% (OR: 1.08; 95% CI: 1.04-1.11; p < 0.001) for every 1 pg/ml increase in IL-6 serum level, both in unadjusted and adjusted analyses (6%; OR: 1.06; 95% CI: 1.02-1.10; p = 0.001).Conclusion: The study supports the usefulness of IL-6 as a predictive biomarker for stroke recurrence after acute ischemic stroke.
