Objectives: Different inflammatory processes and sepsis can significantly affect the number of platelets and platelet indices. Therefore, in this study, total platelet count (PLT), thrombocrit (Pct), platelet distribution width (PDW), mean platelet volume (MPV), and platelet-large cell ratio (P-LCR) were analyzed in patients with Gram-negative and Gram-positive bacterial sepsis and in sterile blood cultures. Materials and methods: Inclusion criteria were an increased number of inflammatory parameters (elevated values of leukocytes, C-reactive protein (CRP), procalcitonin (PCT), and positive blood culture. Exclusion criteria were patients who did not have elevated values of inflammatory parameters and did not have a positive blood culture. Samples were collected from patients who had sepsis confirmed by blood cultures at the Department of Microbiology and Molecular Diagnostics at University Clinical Hospital Mostar in the period from 2019 to 2022. Three groups were analyzed, patients who had sterile blood cultures, patients with blood cultures with isolated Gram-positive bacteria, and patients with blood cultures with isolated Gram-negative bacteria. Specific infectious agents were identified for each group of patients. In addition to the above, PLT, Pct, MPV, PDW, P-LCR, PCT, CRP, the total number of leukocytes, and the number of neutrophil leukocytes were analyzed in each group. Results: The values of PCT, CRP, and the number of neutrophile leukocytes were significantly higher in patients with Gram-negative sepsis as compared to Gram-positive sepsis and to control group. Patients with sepsis have decreased PLT and Ptc and increased values of MPV, PDW, and P-LCR. In sepsis caused by the Gram-negative bacteria, i.e., Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii, the values of the same parameters were more changed compared to sepsis caused by Gram-positive bacteria, i.e., Streptococcus pneumoniae, Enterococcus spp., and methicillin-resistant Staphylococcus aureus (MRSA). When comparing Gram-negative negative bacteria, PLT was lowest in sepsis caused by Escherichia coli, the PDW value was highest in sepsis caused by Acinetobacter baumannii, and MPV and P-LCR were the highest in sepsis caused by Klebsiella pneumoniae. Conclusion: Our study showed that platelet indices are significantly changed in patients with sepsis. Patients with sepsis have decreased values of PLT and Pct and increased values of MPV, PDW, and P-LCR, indicating an increase in thrombocyte production. Moreover, the results were more prominent in sepsis caused by Gram-negative bacteria compared to sepsis caused by Gram-positive bacteria.

Neutropenic enterocolitis (NE) is a potentially life-threatening condition, primarily affecting neutropenic patients with hematologic malignancies. The clinical manifestations of NE in patients receiving antineoplastic drugs range from fever, diarrhea, nausea, vomiting, and abdominal pain to intestinal perforation and shock. We report the case of a 12-year-old boy with acute myelogenous leukemia, undergoing chemotherapy, who presented with an atypical case of NE. Due to numerous jejunal perforations and severe rectal bleeding, he experienced abdominal distension without any accompanying tenderness and the unexpected rapid onset of shock. Surgery was performed, and his postoperative course was uneventful. However, seven days later, Pseudomonas aeruginosa-induced sepsis made his condition rapidly worse due to severe neutropenia and thrombocytopenia. Despite intensive supportive therapy, the patient unfortunately passed away. NE remains a life-threatening complication in pediatric immunosuppressed leukemic patients. A high index of suspicion, prompt diagnosis, aggressive treatment with broad-spectrum antibiotics, and correction of fluid-electrolyte imbalances are crucial in reducing morbidity and mortality.

Acute pulmonary embolism (PE) management guidelines categorize normotensive patients with right ventricle dysfunction (RVD) and normal cardiac troponin (cTn) as intermediate low risk. This study explores the prevalence of cardiovascular comorbidities and their impact on risk stratification in this specific cohort. To investigate the characteristics of normotensive acute PE patients with RVD and normal cTn, emphasizing the role of pre-existing cardiovascular diseases in determining the intermediate-low risk status. A total of 1675 PE patients from a regional registry were screened, excluding high-risk and intermediate-high-risk cases. Among the remaining 400 normotensive patients with RVD, 353 with echocardiography and normal cTn were included. Patients were categorized into low or intermediate-low risk based on RVD presence. Cardiovascular comorbidities were assessed, and logistic regression analyzed their association with intermediate-low risk. Intermediate-low-risk patients (n=137) exhibited significantly higher rates of chronic heart failure, arterial hypertension, coronary artery disease, diabetes, and atrial fibrillation compared to low-risk patients (n=216). A substantial 77.4% of intermediate-low-risk patients had at least one cardiovascular comorbidity, significantly elevating the risk of RV dysfunction (adjusted OR 2.954, p<0.001). The all-cause hospital mortality was 5.1% in intermediate-low-risk and 1.4% in low-risk PE. Normotensive acute PE patients with RVD and normal cTn are predominantly burdened with chronic cardiovascular conditions. The majority of intermediate-low-risk patients have at least one cardiovascular comorbidity, indicating an increased risk of death during hospitalization compared to low-risk patients. This study underscores the necessity for nuanced risk stratification considering pre-existing cardiovascular diseases for tailored and effective management. These findings have important implications for optimizing treatment strategies and improving outcomes in this high-risk population.

Active malignant disease is associated with pulmonary embolism and the treatment of this condition is very challenging. The efficacy and safety of thrombolytic therapy for acute severe PE in patients with active malignant disease is unknown. This study aimed to investigate hospital mortality rate and the incidence of major bleeding at 7 days according to the International Society of Thrombosis and Hemostasis (ISTH) criteria in patients with active malignant disease who were treated with thrombolytic therapy due to severe acute PE. Patients with acute PE proven by computed tomography pulmonary angiography who were admitted to intensive care units have enrolled in the Regional PE Registry (REPER) since 2015, consisting of 10 hospitals from the 4 east Balkan countries. The decision to use thrombolytic therapy was at the discretion of the attending physicians, and it was used in high-risk, and intermediate-high-risk PE patients. Hospital mortality and the incidence of major bleeding at 7 days were compared between patients with active cancer and those without it who received thrombolytic therapy. Alteplase-based therapy was used. Among 2070 patients with acute PE enrolled in REPER, intermediate-high and high-risk PE had 795 patients without malignant disease and 135 had active malignant disease in the last 6 months. Patients with malignant disease had less chance to be treated with thrombolysis than patients without it (29.1% vs 44.7%, OR 0.508, 95%CI 0.341-0.756, p=0.001). For patients treated with thrombolysis, hospital mortality was non significantly higher in patients with the malignant disease compared to patients without it (25.6% vs 16,1%, OR 1.803, 95%CI 0.833-3.904, p=0.132), and the incidence of major bleeding at seven days was similar (15.4% vs 18.5%, OR 0.800, 95%CI 0.322-1.989, p=0.6131). There was no significant difference in age, sex, and PE risk distribution between patients with active malignant disease and those without it who were treated with thrombolysis. Thrombolytic therapy seems to be underutilized in patients with the active malignant disease compared to patients without it in severe acute PE. In the selected patients who were treated with thrombolysis for severe acute PE, the efficacy and safety are similar between patients with and without active malignant disease.

Background/Objectives: The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire is a widely employed self-report tool for assessing upper extremity function. The aim of this study was to assess the psychometric properties of the Serbian version of the DASH by determining its criterion and construct validity, as well as internal consistency. Methods: This cross-sectional study was conducted among patients with hand and wrist disabilities at the Institute for Orthopedics “Banjica”, Serbia. The psychometric properties of the Serbian version of the DASH were analyzed through an examination of its factorial structure and internal consistency. The DASH consists of 30 items, 24 of which assess function, 21 of which focus on physical function and three on social/role function. The remaining six items evaluate symptoms related to pain, tingling/numbness, weakness, and stiffness. Results: A total of 297 patients were included in the study. The mean age was 47.4 ± 16.8 years, with 50.5% males. Three models were assessed to determine the reliability and validity of the questionnaire across different domains. Model 1 examined a single-factor structure. In Model 2, the items were divided into two domains: Physical Function and Psychosocial/Symptoms. In Model 3, items were subdivided into three domains: Physical Function, Symptoms, and Psychosocial. All models demonstrated an excellent internal consistency with a Cronbach’s alpha > 0.9 for most domains. The values for the fit indices Tucker–Lewis index (TLI) and Comparative-Fit Index (CFI) were above their cut-off criteria of 0.9, while the Root Mean Square Error of Approximation (RMSEA) and Standardized Root Mean Square Residual (SRMR) were below the suggested value of 0.06, indicating an excellent level of models fit. Standardized factor loadings were statistically significant (p < 0.05). Conclusions: The present study provided the evidence for the appropriate metric properties of the Serbian version of the DASH. Results support both the unidimensional and multidimensional structures of the DASH.
