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.

Objectives: The aim of this study was to determine the disturbances in the concentration of parathyroid hormone (PTH) and 25-hydroxyvitamin D (vitamin D) in patients with stable chronic obstructive pulmonary disease (COPD) and its correlation with airflow obstruction. Materials and methods: A prospective study included 200 patients with a confirmed diagnosis of COPD in the Department of Lung Diseases and Tuberculosis and Pulmonology Polyclinic of University Clinical Hospital Mostar in the period of three years, between May 2021 and May 2024. Inclusion criteria were a stable phase of COPD, hemodynamically stable patients older than 40 years, forced vital capacities in the first second (FEV1)/forced vital capacities (FVC) <0.7, and patients with PTH, vitamin D, calcium, and phosphate measurements. Exclusion criteria were acute exacerbation of COPD in the last month; current treatment with nutritional supplements, vitamins, and statins; lack of availability of lung function data; use of systemic corticosteroids in the previous three months; chronic renal insufficiency, respiratory diseases other than COPD (asthma, pneumonia, tuberculosis, and bronchiectasis), and other diseases (cancer and parathyroid disease). Medical records about demographic data (age and gender), pulmonary function test (FVC, FEV1, FEV1%FVC, mean expiratory flow (MEF)50), body mass index (BMI), COPD assessment test (CAT), Modified Medical Research Council (mMRC) Dyspnea Scale, and serum PTH, vitamin D, calcium, and phosphate levels were obtained. Results: Patients with higher COPD stage had lower spirometry values, most significantly MEF50. The higher the COPD group (Global Initiative for Chronic Obstructive Lung Disease (GOLD) D), the lower vitamin D and the higher PTH levels were. Calcium and phosphate values were the same for all groups. Vitamin D and PTH levels significantly correlated with MEF50 values. The lower MEF50 level, the higher PTH levels, and lower vitamin D levels were found (P<0.05). Conclusion: Our study showed that the patients in the higher COPD group have lower vitamin D levels and higher PTH levels, indicating that they developed secondary hyperparathyroidism. The levels of vitamin D and PTH correlated the most with MEF50 values while other spirometry parameters did not significantly correlate with vitamin D and PTH levels.

Objectives: The aim of this study was to determine the short-term consequences of coronavirus disease 2019 (COVID-19) infection on pulmonary diffusion in patients with severe (but not critical) and moderately severe COVID-19 pneumonia during three months after COVID-19 infection. Methods: A prospective study included 81 patients with an RT-PCR-test confirmed diagnosis of COVID-19 infection treated in the COVID Department of Lung Diseases of University Clinical Hospital Mostar. Inclusion criteria were ≥18-year-old patients, COVID-19 infection confirmed using real-time RT-PCR, radiologically confirmed bilateral COVID-19 pneumonia, and diffusion capacity of the lungs for carbon monoxide (DLCO) one and three months after COVID-19 infection. The pulmonary function was tested using the MasterScreen Body Jaeger (Jaeger Corporation, Omaha, USA) and MasterScreen PFT Jaeger (Jaeger Corporation, Omaha, USA) according to American Thoracic Society guidelines one and three months after COVID-19 infection. Results: Forced vital capacity significantly increased three months after COVID-19 infection compared to the first-month control (p<0.0005). Also, a statistically significant increase in the FEV1 value (p<0.0005), FEV1%FVC ratio (p<0.005), DLCO/SB (p<0.0005), DLCO/VA value (p<0.0005), and total lung capacity (TLC) (p<0.0005) was observed in all patients. Conclusion: Our study showed that recovery of DLCO/VA and spirometry parameters was complete after three months, while DLCO/SB was below normal values even after three months. Therefore, one month after the COVID-19 infection patients had partial recovery of lung function, while a significant recovery of lung function was observed three months after the COVID-19 infection.

BACKGROUND Personality traits as alexithymia and type D personality may impair health related quality of life (HRQoL) in patients with irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Aim of this study was to evaluate personality traits in patients with IBS and IBD and their impact on HRQoL. MATERIALS AND METHODS The subjects (40 patients with IBS, 40 with IBD and 40 health control subjects) completed SF-36 questionnaire, TAS-20 and DS14 scale. RESULTS Patients with IBS and IBD had higher results on TAS-20 and DS14 scale when compared with healthy controls. Also IBS patients had higher scores than IBD patients. Higher scores on TAS-20 and DS14 scales in IBS and IBD patients correlate with lower HRQoL. HRQoL was poorer in IBS and IBD patients than in healthy control subjects. CONCLUSIONS Alexithymia and type D personality in IBS and IBD patients are associated with lower HRQoL and psychological interventions should be considered.

Distant abscesses are uncommon during the episode of acute pancreatitis (AP). However, these are possible sequalae of necrotizing pancreatitis and should be treated appropriately to prevent serious septic complications. We demonstrate a case of a 56-year-old male patient who presented with severe necrotizing pancreatitis and distant retroperitoneal abscess that reached femoral region and was detected on diagnostic imaging scans. Combination of surgical and supportive therapy was employed, and the patient recovered well with no permanent consequences. Our article highlights the importance of quick and accurate diagnosis and timely intervention in this rare type of pancreatitis complication.

Recent studies have established a concept of tumour necrosis factor‐α (TNF‐α)/Fas signalling crosstalk, highlighting TNF‐α as a critical cytokine in sensitizing hepatocytes to death induced by Fas activation. However, in the exact inflammatory response, besides TNF‐α, many other mediators, that might modulate apoptotic response differentially, are released. To resolve the issue, we studied the effects of lipopolysaccharide (LPS), one of the crucial inductors of inflammation in the liver, on apoptotic outcome. We show that LPS‐induced inflammation diminishes the sensitivity of hepatocytes to Fas stimulus in vivo at caspase‐8 level. Analysis of molecular mechanisms revealed an increased expression of various pro‐inflammatory cytokines in non‐parenchymal liver cells and hepatocyte‐specific increase in Bcl‐xL, associated with signal transducer and activator of transcription 3 (Stat3) phosphorylation. Pre‐treatment with ruxolitinib, a selective Janus kinase (JAK) 1/2 inhibitor, prevented the LPS‐induced Stat3 phosphorylation and restored the sensitivity of hepatocytes to Fas‐mediated apoptosis. Furthermore, ruxolitinib pre‐treatment diminished the LPS‐induced Bcl‐xL up‐regulation without an inhibitory effect on LPS‐induced expression of pro‐inflammatory cytokines. In summary, although the reports are showing that the effects of isolated pro‐inflammatory mediators, such as TNF‐α or neutrophils, are pro‐apoptotic, the overall effect of inflammatory milieu on hepatocytes in vivo is Stat3‐dependent desensitization to Fas‐mediated apoptosis.

INTRODUCTION During the plateletpheresis procedure the number of thrombocytes in the donor's blood significantly decreases, and the levels of the hematocrit (HCT), hemoglobin (Hgb), and leukocyte (WBC) diminish as well. Influence of the cell separator is one of the factors that affects the levels of HCT, Hgb and WBC. In this study, the goal was to determine the value difference of HCT, Hgb, WBC, and platelets after the platelet pheresis process between performance on Fenwal AMICUS and on Fresenius Com Tec. DONORS AND METHODS The criteria for participation: male in the age range of 25-45. We have formed two groups: for both groups - 180 separations were performed on 60 participants were the values of hematocrits, concentration of hemoglobin and number of leukocytes were established before and after separation using the double-needle continuous flow cell separation (DN-CFCS) on two different devices, Fenwal AMICUS device and the Fresenius Com Tec. device. To confirm the statistical differences we have used Student t-test for independent or dependent samples, as well as Mann-Whitney U test as non-parametric alternative. To compare differences between the values of four parameters (P1-P2) from two groups (using two devices - Fenwal AMICUS and Fresenius Com Tec) The possibility of errors were accepted for α<0.05, and the difference between groups as statistical relevant were accepted for p<0.05. RESULTS Statistically significant lower values were noted for all researched parameters after separation on both devices. The statistically significant average values for Hct, Hgb and WBC obtained between two devices, were less than 0.05 (p=0.05). For the platelets (Plt) there was no statistical significant difference (p>0.05 - α=0.05), between average level obtained using either Fenwal AMICUS or Frazenius Com Tec. CONCLUSION The type of cell separator had the influence on the decrease value of the observed parameters.

Classification of acute heart failure (AHF) patients into four clinical profiles defined by evidence of congestion and perfusion is advocated by the 2016 European Society of Cardiology (ESC)guidelines. Based on the ESC‐EORP‐HFA Heart Failure Long‐Term Registry, we compared differences in baseline characteristics, in‐hospital management and outcomes among congestion/perfusion profiles using this classification.
