Heavy metals are a major toxicological concern due to their adverse effects on human health, particularly in children exposed to contaminated areas. This study evaluated biomarkers of exposure in 253 children aged 6 to 12 from Magangue, Achi, and Arjona (Bolivar, Colombia), analyzing their relationship with neurotoxicity and hematological markers. The mean Pb concentrations at the study sites were 1.98 µg/g (Magangue) > 1.51 µg/g (Achi) > 1.24 µg/g (Arjona). A similar pattern was observed for Cd concentrations for Magangue (0.39 µg/g) > Achi (0.36 µg/g) > Arjona (0.14 µg/g). In contrast, Se concentrations followed a different trend for Arjona (0.29 µg/g) > Magangue (0.21 µg/g) > Achi (0.16 µg/g). The proportion of Se/Pb molar ratios > 1 was higher in Arjona (3.8%) than in Magangue (0.9%) and Achi (2.0%). For Se/Cd ratios, values > 1 were also more frequent in Arjona (70.7%), exceeding 20% in the other two locations. Significant differences were found among locations in red and white blood cell parameters and platelet indices. Neurotransmitter-related biomarkers, including serotonin, monoamine oxidase A (MAO-A), and acetylcholinesterase levels, also varied by location. Principal component analysis showed that Pb and Cd had high loadings on the same component as PLT, WBC, and RDW, and while Se loaded together with HGB, PDW, MCHC, MCH, and MCV, suggesting distinct hematological patterns associated with each element. Multiple linear regression analysis demonstrated a statistically significant inverse association between hair Pb levels and serotonin concentrations. Although MAO-A and Cd showed negative β coefficients, these associations were not statistically significant after adjustment. These findings highlight the potential impact of toxic element exposure on key hematological and neurochemical parameters in children, suggesting early biological alterations that may compromise health and neurodevelopment.

Background: Reliable platelet (PLT) measurement is crucial for the accurate diagnosis of thrombocytopenia. Several methods exist for automated PLT counting, including the impedance method (PLT-I), as well as optical and fluorescence methods (PLT-F). The impedance method is cost-effective but susceptible to interference from small red blood cells and schistocytes. In contrast, fluorescent assessment offers higher specificity but is more expensive, as it requires additional dyes and detectors. Hybrid platelet counting (PLT-H) combines impedance with measurements from the leukocyte differentiation channel and is available without additional cost. Aim: The aim of this study was to evaluate the accuracy of hybrid PLT counting in anemic samples. Methods: In this retrospective study, PLT counts from 583 unselected anemic samples were analyzed using two different analyzers: the Sysmex XN3500, equipped with fluorescent PLT-F technology, and the Mindray BC6200, which uses both impedance (PLT-I) and hybrid (PLT-H) technologies. Agreement between PLT-I and PLT-F, as well as between PLT-H and PLT-F, was assessed using Bland–Altman plots. Correlation between the methods was evaluated using the Pearson correlation coefficient. Results: The hybrid method demonstrated better accuracy in PLT counting compared to the impedance method. Correlation between PLT-H and PLT-F was excellent, ranging from 0.991 to 0.999. In thrombocytopenic samples (PLT < 50 G/L), the hybrid method also provided more reliable PLT counts than the impedance method, reducing the number of falsely elevated PLT results by nearly fivefold. Conclusions: Hybrid platelet counting yields more accurate results than the impedance method in anemic samples and shows excellent correlation with the fluorescence method. Full article

Objectives: This study sought to assess the impact of diabetes and hypertension on wound healing and recovery in orthopedic patients, with an emphasis on laboratory correlations. Materials and Methods: This study included 67 orthopedic patients, divided into a geriatric group (n = 49, ≥65 years) and a control group (n = 18). Clinical and laboratory assessments were performed at admission and discharge. Data were analyzed statistically. Results: Geriatric patients showed a higher triglyceride glucose-body mass index (TyG-BMI), glucose, cholesterol, C-reactive protein (CRP), interleukin-6 (IL-6), and leukocytes and lower hemoglobin and platelets (PLTs), with poorer healing and well-being. Elevated CRP, IL-6, and urea and decreased protein and hemoglobin persisted in this group. Diabetes improved outcomes in older adults, while hypertension worsened them in younger patients. Favorable outcomes correlated with higher triglycerides, fibrinogen, hemoglobin, and red blood cells (RBCs), while they did not correlate with elevated CRP, IL-6, leptin, urea, creatinine, and white blood cells (WBCs). Conclusions: Key predictors of healing and well-being included CRP, hemoglobin, RBC, and hematocrit in older patients and hypertension, CRP, hemoglobin, and leptin in younger individuals. Age-specific metabolic and inflammatory profiles influence recovery trajectories and may be used to predict problems in both recovery and patients’ well-being. Further research is required to better understand the correlations between these factors. Full article

Objectives: Kawasaki Disease (KD) is an acute vasculitis associated with systemic inflammation. This study aimed to investigate the level and clinical significance of soluble ST2 (sST2) in children with KD. Methods: A retrospective analysis was conducted on 287 pediatric KD patients treated at the Pediatric Cardiology Department of Shengjing Hospital, China Medical University, from November 2021 to December 2022. Patients were stratified into subgroups based on the presence of myocardial damage (MD), coronary artery lesions (CAL), multi-organ involvement (MOD; ≥3 organs) and/or intravenous immunoglobulin-resistant KD (IVIG-R KD). In each group, we analyzed the correlation between sST2 levels and various laboratory parameters, including white blood cell count (WBC), hemoglobin (HB), platelet count (PLT), C-reactive protein (CRP), interleukin-6 (IL-6), erythrocyte sedimentation rate (ESR), N-terminal pro-brain natriuretic peptide (NT-pro BNP), D-dimer, and albumin (ALB). Results: Patients in the CAL group were significantly younger and predominantly male (p < 0.05). In the MD, CAL, MOD, and IVIG-R KD groups, levels of sST2, CRP, NT-pro BNP, and D-dimer were significantly higher than in their respective comparison groups (p < 0.05). sST2 showed weak positive correlations with WBC, CRP, IL-6, NT-pro BNP, and D-dimer, and weak negative correlations with HB and ALB (p < 0.05). sST2, HB, and IL-6 were identified as independent risk factors for MOD (p < 0.05). sST2 and HB were independent risk factors for IVIG-R KD (p < 0.05). Among acute-phase patients, four cases had sST2 levels > 200 ng/mL—all were classified as IVIG-R KD and MOD; three of these also developed coronary artery aneurysms (CAA). Conclusions: Elevated sST2 levels in the acute phase of KD may serve as a clinical indicator of IVIG-R KD, CAA, MOD, and MD. Full article

Background/Objectives: Miscarriage is a common pregnancy complication that significantly impacts individuals’ health due to its physical and psychological effects. This study aimed to investigate the association between periodontal health and hematological parameters in women who experienced miscarriage before the 20th week of gestation, and to assess the potential predictive value of these parameters for miscarriage risk by comparing them with those of women with an uncomplicated pregnancy course. Methods: This study was a prospective case–control and cross-sectional study. It included a total of 82 participants, comprising 41 women with miscarriage and 41 healthy pregnant controls. The periodontal examinations included measurements of the Gingival Index (GI), Plaque Index (PI), Probing Depth (PD), Clinical Attachment Loss (CAL), and Simplified Calculus Index (SCI). Additionally, complete blood counts (CBCs) were obtained from all participants. Appropriate statistical analyses, including non-parametric, correlation, logistic regression, and ROC analyses, were conducted, with the significance level set at p < 0.05. Results: The primary outcome measure was CAL as an indicator of periodontal disease severity and its association with miscarriage risk. Additional outcomes included Plateletcrit (PCT), the Platelet Count (PLT), and the Neutrophil-to-Lymphocyte Ratio (NLR) to evaluate systemic inflammatory responses and their correlations with periodontal parameters. CAL was significantly elevated in the miscarriage group (p < 0.001) and emerged as the strongest predictor of miscarriage risk (OR = 0.0537, p < 0.001, AUC = 0.8691). PCT was significantly higher in the miscarriage group (p = 0.017) and positively correlated with the GI (p = 0.041), suggesting a link between systemic inflammation and periodontal health. Conclusions: Considering this study’s limitations, CAL was the strongest predictor of miscarriage, while PLT and PCT had some discriminative power. Collaboration between obstetricians and dentists can facilitate early diagnosis and intervention by promoting routine oral health check-ups before and during pregnancy. Additionally, integrating oral health assessments into prenatal care and developing public health policies could enhance access to dental services during both preconception and pregnancy periods.

Cardiovascular diseases continue to pose a major global health burden, contributing significantly to mortality rates worldwide. This study aimed to explore the association between myocardial infarction and basic hematological parameters—red blood cells (RBCs), white blood cells (WBCs), and platelets (PLTs)—which are routinely assessed in clinical diagnostics. The analysis was conducted on a cohort of 743 adults hospitalized with diagnosed cardiovascular conditions. To identify blood parameters that distinguish patients with a history of first-time myocardial infarction from those who had never experienced such an event, we employed a dual analytic approach. Standard parametric methods were complemented with bootstrap resampling to strengthen inference and mitigate the impact of sampling variability. Patients with myocardial infarction showed decreased RBC and elevated WBC counts relative to those without infarction. These associations were non-linear, with the most pronounced group differences observed within the second and third quartiles of RBC and WBC distributions, while minimal differences appeared at the distributional extremes. No significant differences were found in platelet count (PLT) between the groups. Bootstrap validation not only corroborated findings obtained through traditional statistics, but also enhanced the robustness of the results, providing improved estimates under data conditions prone to skewness or small sample artifacts. This approach enabled the detection of nuanced patterns that might elude classical inference. Our findings emphasize the utility of resampling techniques in clinical research settings, particularly where inference stability is critical. Incorporating such methods in future investigations may advance statistical rigor, increase reproducibility, and better capture complex biological relationships in medical datasets. Full article

Background: The radial forearm free flap (RFFF) is a common technique in head and neck reconstructive surgery. This study aimed to compare the clinical and biochemical outcomes of wound healing following ulnar-based transposition flap (UBTF) versus split-thickness skin grafting (STSG) for donor site closure, with a particular emphasis on tissue regeneration. Materials and Methods: A total of 24 patients (6 women, 18 men), underwent RFFF reconstruction. The donor site was closed using the UBTF technique in 10 cases, while STSG was performed in 14 cases. Postoperative complications—including necrosis, edema, hematoma, infection, and wound dehiscence—along with healing times were assessed daily during the first seven postoperative days and at monthly follow-ups over six months. Pre- and postoperative biochemical analyses included hemoglobin (HB), white blood cell count (WBC), platelets (PLT), albumin, and C-reactive protein (CRP) levels. An aesthetic evaluation of the flap was also performed. Results: The two groups were homogeneous. Postoperative complications occurred more frequently in the STSG group, which also demonstrated significantly longer healing times (p = 0.0004). In contrast, the UBTF group showed significantly better aesthetic outcomes in terms of skin color (p = 0.000021), skin texture (p = 0.000018), and flap stability (p = 0.0398). Additionally, pre- and postoperative PLT counts were significantly higher in the UBTF group (p = 0.001 and p = 0.043, respectively). Conclusions: While STSG remains a well-established method for forearm donor site closure following RFFF harvest, this study demonstrates that UBTF is a viable alternative associated with better clinical and aesthetic outcomes.

The amygdala, especially its central nucleus (CeA), is one of the key brain structures regulating fear, anxiety and stress responses and is also involved in gut microbiota signal processing. Amygdala hyperactivity, as well as microbiota alterations, plays an important role in the pathophysiology of anxiety disorders, depression or post-traumatic stress disorder (PTSD). The present study determines whether 3 weeks of galactooligosaccharide (GOS) supplementation alleviates behavioural, haematological, immunological and gut microbiota disturbances induced by long-term electrical stimulation of the CeA in rats (Stim). The unsupplemented Stim group showed locomotor hyperactivity and higher anxiety (measured with an actometer and the elevated plus maze, respectively), as well as a decrease in white blood cells (WBCs), lymphocytes (LYMs), red blood cells (RBCs) and platelets (PLTs); an elevation of TNFα; a reduction in IL-10 concentration in plasma; and microbiota alterations as compared to the control (Sham) group. GOS supplementation alleviated all these Stim-induced adverse effects or even normalised them to the sham group level. The effect of GOS was comparable to citalopram and even more effective in WBC and PLT normalisation and IL-10 induction. The obtained results indicate the high therapeutic potential of GOS in anxiety and stress-related disorders. GOS supplementation may support conventional therapy or the prevention of PTSD, depression and anxiety disorders. Full article

Background: Physical activity in elderly adults reduces the risk of numerous diseases, enhances their quality of life, and improves their physical performance and overall strength. This study aimed to evaluate the effects of smovey^® exercise on morphological and rheological blood parameters in a group of women over 60 years of age. Methods: The study included 30 women aged 71.08 ± 6.41 years, with a control group of 15 age-matched women. Participants in the experimental group underwent a three-month smovey^® training program, consisting of two 45 min sessions per week. The control group did not engage in any regular physical activity. Blood samples were collected from the experimental group before and after the training period, while in the control group, blood was collected once. Results: After three months of smovey^® training, a statistically significant increase in red blood cell, hemoglobin, and platelet counts was observed. Smovey^® training also enhanced erythrocyte deformability at the lowest shear force. Conclusions: Smovey^® training leads to changes in the morphological properties of blood in elderly women, leading to increases in RBC, HGB, PLT, and MCHC indices. Additionally, smovey^® training improves erythrocyte deformability at a shear stress of 0.30 [Pa], reducing the half-time of complete aggregation. Full article

Background: This study aimed to compare the clinical, pathological, and biochemical characteristics of upper rectal cancer (URC) and mid–lower rectal cancer (MLRC) in stage II and III non-metastatic rectal cancer and to identify distinct prognostic factors influencing survival and recurrence. Material and Methods: This retrospective cohort study included 100 patients with stage II and III non-metastatic rectal adenocarcinoma who underwent neoadjuvant chemoradiotherapy (nCRT) followed by curative-intent surgery between 2021 and 2024. Patients were categorized into URC (n = 53) and MLRC (n = 47) groups. Parameters analyzed included demographic factors, ASA score, surgical characteristics, pathological features (tumor stage, lymph node involvement, lymphovascular invasion (LVI), perineural invasion (PNI), tumor budding, tumor regression grade (TRG)), and biochemical markers (carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), white blood cell (WBC) count, neutrophil count, platelet count (PLT), and C-reactive protein (CRP)). One-year overall survival (OS) and disease-free survival (DFS) were analyzed using Kaplan–Meier survival curves, and Cox regression models identified independent prognostic factors. Results: Preoperative CEA levels were higher in MLRC (p = 0.05), whereas WBC count (p = 0.01), neutrophil count (p = 0.02), PLT (p = 0.01), and CRP levels (p = 0.01) were higher in URC. Pathological analysis revealed higher LVI (p = 0.04), PNI (p = 0.04), and tumor budding (p = 0.03) in MLRC. At one-year follow-up, OS rates were 82.1% (URC) vs. 80.3% (MLRC) (p = 0.85), and DFS rates were 78.6% (URC) vs. 73.4% (MLRC) (p = 0.72). Multivariate Cox regression analysis identified age (HR: 1.04, p = 0.03), ASA score (HR: 1.22, p = 0.01), CRP (HR: 1.18, p < 0.001), preoperative CEA (HR: 1.12, p = 0.02), preoperative CA19-9 (HR: 1.09, p = 0.03), LVI (HR: 1.42, p < 0.001), PNI (HR: 1.35, p = 0.02), and tumor budding (HR: 1.28, p = 0.03) as independent prognostic factors for OS. Similar trends were observed for DFS, with T stage (HR: 1.35, p = 0.01) and tumor size (HR: 1.22, p = 0.01) also being found significant. Conclusions: Inflammatory markers, tumor burden indicators (LVI, PNI, budding, tumor size, T stage), and preoperative CEA/CA19-9 were identified as significant predictors, suggesting a risk-adapted approach to rectal cancer treatment.

Crimean–Congo hemorrhagic fever (CCHF) is a tick-borne zoonotic disease, causing clinical presentations ranging from asymptomatic infection to fatal viral hemorrhagic fever. Throughout the course of CCHF, the levels of certain biomarkers, such as platelets (PLTs), white blood cells (WBCs), C-reactive protein (CRP), and interleukin-6 (IL-6), may vary, decreasing below or rising above normal limits. This study aimed to investigate the role of parameters such as WBC/PLT, WBC/IL-6, WBC/CRP, and WBC/D-dimer ratios in predicting disease prognosis in patients diagnosed with CCHF. The study population consisted of 60 CCHF patients and 30 controls. Statistically significant differences were observed in hemoglobin (HGB), PLT, WBC, activated partial thromboplastin time (aPTT), international normalized ratio (INR), fibrinogen, and d-dimer values between the patients and controls. Statistically significant differences were observed in WBC/aPTT, WBC/fibrinogen, WBC/D-dimer, and WBC/IL-6 values between the patient and control groups. WBC/INR and WBC/fibrinogen values were lower in fatal cases compared to survivors. WBC/D-dimer and WBC/IL-6 values, on the other hand, were higher in fatal cases compared to survivors. In patients requiring intensive care unit (ICU), WBC/PLT, WBC/INR, WBC/aPTT, and WBC/fibrinogen values were higher compared to those who did not. However, WBC/D-dimer and WBC/IL-6 values were lower in patients requiring ICU compared to those who did not. Full article

Background: The role of radioiodine (RAI) therapy for differentiated thyroid cancers (DTCs) is still a matter of debate. Low-dose RAI (LDRAI) therapy is a possible treatment for patients at low–intermediate risk of recurrence. The aim of this study was to evaluate the occurrence of post-RAI therapy clinical and biochemical side effects with respect to its dosage. Methods: We retrospectively examined 142 patients who had been administered RAI therapy for DTCs and carried out at least a 12-month follow-up. The incidence of clinical adverse events (CAEs: xerophthalmia, xerostomia, and dysgeusia) and values for hemoglobin (Hb), red blood cells (RBCs), white blood cells (WBCs) and platelets (PLTs) during the first year of follow-up were compared between patients who underwent standard-dose RAI (SDRAI) therapy and LDRAI therapy. Results: Of the 142 patients, 66 were treated with LDRAI and 76 with SDRAI. A higher incidence of CAEs was found in the SDRAI group than in the LDRAI group (p = 0.002). An administered dose above 2849 MBq was associated with CAEs (sensitivity 88.89%, specificity 54.03%, p < 0.001). We found a slight decrease in Hb (p = 0.008), RBCs (p = 0.013), WBCs (p = 0.004) and PLTs (p < 0.001) in the SDRAI group, while in the LDRAI group only WBCs showed a minimal decrease (p = 0.027) with any occurrence of overt bone-marrow disease. Conclusions: According to our data, LDRAI therapy seemed to be associated with a lower incidence of CAEs than SDRAI therapy. Both methods showed an excellent safety profile in terms of hematopoietic effects. However, the effect of SDRAI therapy in this setting might have been more positive than that of LDRAI therapy.

Background: Thrombospondin-1 (TSP1) is a multimeric glycoprotein that is increasingly recognized as a mediator of metabolic, thrombotic, and inflammatory processes. Although TSP1 expression has been associated with adipose tissue dysfunction and insulin resistance, the precise relationship with obesity severity remains unclear. Endothelin-1 (ET1), another important regulator of vascular homeostasis, may also contribute to obesity-related cardiometabolic risk, with evidence suggesting sex-specific differences, including delayed onset in women. The study aimed to investigate circulating TSP1 and ET1 levels in a cohort of nondiabetic obese female adults, evaluate their associations with metabolic and inflammatory parameters, and determine whether these markers differ according to obesity severity and related disease risk. Methods: Fifty-five nondiabetic women with obesity and no history of cardiovascular events were enrolled at the Endocrinology Unit (“R. Dulbecco” Univ. Hospital, Catanzaro, Italy). Anthropometric and clinical data, together with hematological and coagulation parameters and metabolic indices (HOMA-IR, HbA1c, and lipid profile), were evaluated. TSP1 and ET1 concentrations were measured using automated enzyme immunoassays (ELISAs). The participants were stratified by BMI (30–34.9 vs. ≥35 kg/m²) into low-risk and moderate/high-risk obesity based on the WHO classification, and correlations between biomarkers and metabolic/inflammatory parameters were evaluated. Results: The median BMI was 33.7 kg/m², with 52% of participants having moderate/high-risk obesity (WHO Class II/III). A significant proportion (69.8%) showed insulin resistance (HOMA-IR > 2.5). TSP1 was positively correlated with white blood cell count (WBC, r = 0.354, p < 0.01), platelet count (PLT, r = 0.411, p < 0.01), and glycated hemoglobin (r = 0.391, p < 0.01), suggesting an association with both inflammation and glycemic control. ET1 was positively correlated with liver enzymes and triglycerides but negatively correlated with PLT and D-dimer. Women with moderate/high-risk obesity had significantly higher HOMA-IR, D-dimer, and inflammatory markers, in addition to a lower TSP1-to-PLT ratio. Conclusions: In this pilot study, TSP1 and ET1 levels tended to decrease with increasing obesity severity in women but were associated with distinct metabolic and inflammatory profiles. The results support the potential role of TSP1 as a biomarker for obesity-related cardiometabolic risk and highlight the complex interplay between TSP1, ET1, and obesity progression. Further studies may clarify whether targeting TSP1 can ameliorate chronic inflammation and insulin resistance in obesity and the potential sex-specific influences on these mechanisms. Full article

The response to exercise following a rest period may vary among horse breeds based on the importance of the hematological and hematochemical profiles of athletic horses. Ten Standardbred and ten Italian Saddlebred mares were subjected to a 4-week training program after a seasonal rest, and hematological parameters (red blood cells—RBCs; hemoglobin—Hb; hematocrit—Hct; platelets—PLTs; platelet aggregation—AG; aggregation slope—Slope; fibrinogen—Fb), as well as Albumin (Alb) and non-esterified fatty acids (NEFAs), were analyzed. Blood samples were obtained each week during the training program following a simulated exercise performed at T0 and T4 (T0pre-T0post; T1, T2, T3, and T4pre-T4post). A two-way ANOVA revealed an increase in all assessed parameters post vs. pre at T0 and T4 (p < 0.01) and a decrease in PLTs (p < 0.01) at T0 and T4 in both breeds. A significant effect of breed was observed, with higher values for RBCs and Hb at each time point (p < 0.001); Hct at T0 post, T2, T3, and T4 post; and NEFAs (p < 0.001) at T0 post and T4 post in Standardbred compared to Saddlebred horses. Positive correlations were identified among RBCs, Hb, Hct, PLTs, Alb, and NEFAs in both breeds and between AG and Slope in Saddlebred horses. Negative correlations were identified among AG and RBCs, Hb, Hct, PLTs, Alb, and NEFAs in Standardbred horses and for AG and Slope with RBCs, Hb, Hct, and PLTs in Saddlebred horses. A comparable reaction to training was observed in both breeds following the seasonal rest. Full article

Background: Asymptomatic liver steatosis constitutes an emerging issue worldwide. Therefore, we decided to explore relationships between selected types of microRNAs (miRNAs), serological markers of liver fibrosis and hematological parameters in the course of non-alcoholic fatty liver disease (NAFLD). Methods: Two hundred and seven persons were included in the survey: 97 with NAFLD and 110 healthy controls. Serological concentrations of miR-126-3p, miR-197-3p, and miR-1-3p were measured in all participants. Direct indices of liver fibrosis [procollagen I carboxyterminal propeptide (PICP), procollagen III aminoterminal propeptide (PIIINP), platelet-derived growth factor AB (PDGF-AB), transforming growth factor-α (TGF-α) and laminin] together with indirect markers (AAR, APRI, FIB-4 and GPR) were also evaluated. The assessment of hematological parameters concerned: mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), red blood cell distribution width (RDW), MPV to platelet (PLT) ratio (MPR), RDW to PLT ratio (RPR), neutrophil to lymphocyte (LYM) ratio (NLR), PLT to LYM ratio (PLR) and RDW to LYM ratio (RLR). Additionally, the NAFLD fibrosis score and BARD score were applied. Results: The concentration of miR-126-3p and miR-1-3p was higher, and miR-197-3p was lower in the NAFLD group (p < 0.0001). miR-197-3p correlated notably with hematological indices: negatively with PDW (p < 0.05) and positively with PLR (p < 0.05). Conclusions: Significant correlations between miRNA molecules and hematological markers in the course of NAFLD indicate inflammation as a potential background and create new possibilities for a diagnostic approach.
