RESUMO
Background Gastric cancer (GC) remains a significant global public health problem, despite the decreasing trends in GC mortality rates in the last five decades. Our study aimed to examine the pattern of GC mortality in Montenegro between 1990 and 2018 and to contribute to the future designing a national long-term strategy for the control and prevention of GC. Methods Gastric cancer mortality data in Montenegro from 1990 to 2018 were collected. Mortality rates were age-standardized to the World Standard Population for estimating both the overall and gender-specific trends. The joinpoint regression model was used to assess GC mortality and identified significant changes in the linear time trend. Linear and Poisson regressions were also applied for additional trend analyses. Results Joinpoint regression reveals a statistically significant decrease in the age-standardized rate for the overall level, on average by 1.4% per year (AAPC (95% IP)= -1.4 (-2.4)-(-0.4); P= 0.007), which was due to a decrease in the age-standardized rate in men with an average annual change of -1.8% (AAPC (95% IP)= -1.8 (-2.9)-(-0.6); P=0.003), while in women the rates were stable (p=0.565). The results for age groups indicate that a decline was registered at the overall level, and among men, as a consequence of the trend of decreasing age-specific rates for the age group 55-64 on average annually by 2% among men (AAPC (95% IP)= -2 ((-3.8)-(-0.1)); P=0.035), and for the overall level (AAPC (95% IP)= -2 ((-3.7)-(-0.3)); P=0.026). Conclusions Our findings indicate a noteworthy decline in age-standardized overall GC mortality rates among men in Montenegro, while rates for women have remained constant. National strategies to further reduce mortality rates for GC are necessary.
RESUMO
BACKGROUND: Patients with acute myeloid leukemia (AML) are at increased risk of venous thromboembolic events (VTE). However, thromboprophylaxis is largely underused. OBJECTIVES: This study aimed to determine possible VTE development risk factors and to develop a novel predictive model. METHODS: We conducted a retrospective cohort study of adult patients with newly diagnosed AML. We used univariate and multivariable logistic regression to estimate binary outcomes and identify potential predictors. Based on our final model, a dynamic nomogram was constructed with the goal of facilitating VTE probability calculation. RESULTS: Out of 626 eligible patients with AML, 72 (11.5%) developed VTE during 6 months of follow-up. Six parameters were independent predictors: male sex (odds ratio [OR] 1.82, 95% confidence interval [CI]: 1.077-2.065), prior history of thrombotic events (OR 2.27, 95% CI: 1.4-4.96), international normalized ratio (OR 0.21, 95% CI: 0.05-0.95), Eastern Cooperative Oncology Group performance status (OR 0.71, 95% CI: 0.53-0.94), and intensive therapy (OR 2.05, 95% CI: 1.07-3.91). The C statistics for the model was 0.68. The model was adequately calibrated and internally validated. The decision-curve analysis suggested the use of thromboprophylaxis in patients with VTE risks between 8 and 20%. CONCLUSION: We developed a novel and convenient tool that may assist clinicians in identifying patients whose VTE risk is high enough to warrant thromboprophylaxis.
RESUMO
BACKGROUND: Oesophageal cancer (OC) is a significant public health issue, despite the decreasing trends in OC mortality rates observed globally in the past decades. The objective of our study is to analyze the pattern of OC mortality in Montenegro between 1990 and 2018 and contribute to the development of a national long-term strategy for the prevention and control of this malignancy. METHODS: The data on OC death cases in Montenegro between 1990 and 2018 were collected. The mortality rates were standardized according to the World Standard Population. The Joinpoint, Linear and Poisson regressions were applied to analyze the OC mortality trend. RESULTS: Joinpoint regression analysis showed an increase in death rates for men and the overall level which were not statistically significant. However, the number of cases increases significantly with an average annual percentage change (AAPC) increase of 2.6% for the overall level [AAPC (95% CI)=2.6 (1.0-4.2); P = 0.002] at the expense of the increase in men, which on average was 2.6% annually [AAPC (95%CI) = 2.6 (1.2-4.1); P = 0.001]. The age groups 55-64 and 65-74 have the highest percentage of deaths cases from OC with 30.6% and 31.4%, respectively. CONCLUSION: Montenegro has witnessed a recent increase in the number of deaths from OC, although the mortality rates remain stable. National strategies to further reduce mortality rates for OC are necessary. Individuals aged 55-64 and 65-74 need specific attention during the ongoing monitoring of this cancer.

OBJECTIVE: The initiation of extracorporeal membrane oxygenation (ECMO) triggers complex coagulation processes necessitating systemic anticoagulation. Therefore, anticoagulation monitoring is crucial to avoid adverse events such as thrombosis and hemorrhage. The main aim of this work was to analyze the association between anti-Xa levels and thrombosis occurrence during ECMO support. DESIGN: Systematic literature review and meta-analysis (Scopus and PubMed, up to July 29, 2023). SETTING: All retrospective and prospective studies. PARTICIPANTS: Patients receiving ECMO support. INTERVENTION: Anticoagulation monitoring during ECMO support. MEASUREMENTS AND MAIN RESULTS: A total of 16 articles with 1,968 patients were included in the review and 7 studies in the meta-analysis (n = 374). Patients with thrombosis had significantly lower mean anti-Xa values (standardized mean difference -0.36, 95% confidence interval [CI] -0.62 to -0.11, p < 0.01). Furthermore, a positive correlation was observed between unfractionated heparin infusion and anti-Xa levels (pooled estimate of correlation coefficients 0.31, 95% CI 0.19 to 0.43, p < 0.001). The most common adverse events were major bleeding (42%) and any kind of hemorrhage (36%), followed by thromboembolic events (30%) and circuit or oxygenator membrane thrombosis (19%). More than half of the patients did not survive to discharge (52%). CONCLUSIONS: This work revealed significantly lower levels of anti-Xa in patients experiencing thromboembolic events and a positive correlation between anti-Xa and unfractionated heparin infusion. Considering the contemplative limitations of conventional monitoring tools, further research on the role of anti-Xa is warranted. New trials should be encouraged to confirm these findings and determine the most suitable monitoring strategy for patients receiving ECMO support.

INTRODUCTION: Thrombopoietin receptor agonists (TPO-RAs) increase platelet counts (PC) in the majority of patients with chronic immune thrombocytopaenia (ITP). Platelet kinetics study (PKS) might contribute to the understanding of mechanisms that lead to durable response. OBJECTIVES: To evaluate the effects of TPO-RAs on PKS parameters in chronic ITP patients. METHODS: Fifteen chronic ITP patients, aged 59 years [range: 22-84], female/male: 10/5, splenectomised 7/15, were treated with TPO-RAs (eltrombopag/romiplostim: 11/4). Durable response was defined as PC ≥30 × 109 /L at 6 months. Autologous 111 Indium-oxinate PKS was performed before and 5 months after TPO-RAs initiation. Accordingly, platelet survival (PS), platelet turnover, production ratio and sequestration site were assessed. RESULTS: Durable response was achieved in 13/15 of patients (eltrombopag/romiplostim: 10/3). Pre-treatment parameters were: PC 10 × 109 /L [range: 1-110], PS 0.5 days [range: 0.1-1.7 (normal values: 7-10)], platelet turnover 30 857 Plt/µL/day [range: 944-103 500] and platelet production ratio 0.64 [range: 0.01-3.2 (normal values: 1 ± 0.2)]. Post-treatment assessment showed significantly higher: PC 92.5 × 109 /L [range: 28-260, p = .001], PS 2.2 days [range: 0.1-3.6, p = .008], platelet turnover 70 213 Plt/µL/day [range: 2800-462 236, p = .02] and platelet production ratio 1.8 [range: 0.5-37.9, p = .011] compared to the pre-treatment values. Platelet sequestration site altered in 3/15 treated with TPO-RAs. CONCLUSIONS: TPO-RAs could increase PC by simultaneous increasing of platelet production and decreasing of platelet destruction.

Although disturbance of redox homeostasis might be responsible for COVID-19 cardiac complications, this molecular mechanism has not been addressed yet. We have proposed modifying the effects of antioxidant proteins polymorphisms (superoxide dismutase 2 (SOD2), glutathione peroxidase 1 (GPX1), glutathione peroxidase 3 (GPX3) and nuclear factor erythroid 2-related factor 2, (Nrf2)) in individual susceptibility towards the development of cardiac manifestations of long COVID-19. The presence of subclinical cardiac dysfunction was assessed via echocardiography and cardiac magnetic resonance imaging in 174 convalescent COVID-19 patients. SOD2, GPX1, GPX3 and Nrf2 polymorphisms were determined via the appropriate PCR methods. No significant association of the investigated polymorphisms with the risk of arrhythmia development was found. However, the carriers of variant GPX1*T, GPX3*C or Nrf2*A alleles were more than twice less prone for dyspnea development in comparison with the carriers of the referent ones. These findings were even more potentiated in the carriers of any two variant alleles of these genes (OR = 0.273, and p = 0.016). The variant GPX alleles were significantly associated with left atrial and right ventricular echocardiographic parameters, specifically LAVI, RFAC and RV-EF (p = 0.025, p = 0.009, and p = 0.007, respectively). Based on the relation between the variant SOD2*T allele and higher levels of LV echocardiographic parameters, EDD, LVMI and GLS, as well as troponin T (p = 0.038), it can be proposed that recovered COVID-19 patients, who are the carriers of this genetic variant, might have subtle left ventricular systolic dysfunction. No significant association between the investigated polymorphisms and cardiac disfunction was observed when cardiac magnetic resonance imaging was performed. Our results on the association between antioxidant genetic variants and long COVID cardiological manifestations highlight the involvement of genetic propensity in both acute and long COVID clinical manifestations.

In SARS-CoV-2 infection, excessive activation of the immune system intensively increases reactive oxygen species levels, causing harmful hyperinflammatory and oxidative state cumulative effects which may contribute to COVID-19 severity. Therefore, we assumed that antioxidant genetic profile, independently and complemented with laboratory markers, modulates COVID-19 severity. The study included 265 COVID-19 patients. Polymorphism of GSTM1, GSTT1, Nrf2 rs6721961, GSTM3 rs1332018, GPX3 rs8177412, GSTP1 rs1695, GSTO1 rs4925, GSTO2 rs156697, SOD2 rs4880 and GPX1 rs1050450 genes was determined with appropriate PCR-based methods. Inflammation (interleukin-6, CRP, fibrinogen, ferritin) and organ damage (urea, creatinine, transaminases and LDH) markers, complete blood count and coagulation status (d-dimer, fibrinogen) were measured. We found significant association for COVID-19 progression for patients with lymphocytes below 1.0 × 109/L (OR = 2.97, p = 0.002). Increased IL-6 and CRP were also associated with disease progression (OR = 8.52, p = 0.001, and OR = 10.97, p < 0.001, respectively), as well as elevated plasma AST and LDH (OR = 2.25, p = 0.021, and OR = 4.76, p < 0.001, respectively). Of all the examined polymorphisms, we found significant association with the risk of developing severe forms of COVID-19 for GPX3 rs8177412 variant genotype (OR = 2.42, p = 0.032). This finding could be of particular importance in the future, complementing other diagnostic tools for prediction of COVID-19 disease course.

BACKGROUND: The goal of research was to investigate the possible relations between serum concentrations of IL-6 and TGF-ß1, individual and clinical characteristics, and adverse effects of radiotherapy in patients with prostate cancer: acute and late genitourinary and gastrointestinal toxicity, and fatigue. METHODS: Thirty-nine patients with localized or locally advanced prostate cancer who were treated with radiotherapy were enrolled in this study. The acute radiotoxicity grades and fatigue levels were assessed during the radiotherapy and 1 month after the radiotherapy. Estimation of the late radiotoxicity was performed every three months in the first year, every four months in the second year, and then every six months. Serum levels of IL-6 and TGF-ß1 were determined before radiotherapy and after the 25th radiotherapy fraction by ELISA. RESULTS: The significant positive association between diabetes mellitus and changes in acute genitourinary toxicity grades during the radiotherapy was observed in prostate cancer patients. In addition, patients who were smokers had significantly higher maximum fatigue levels in comparison with patients who were non-smokers. The circulating IL-6 levels were significantly higher after the 25th radiotherapy fraction in comparison with levels determined before radiotherapy. The significant positive correlations between pretreatment TGF-ß1 levels and maximum genitourinary toxicity grades and between TGF-ß1 levels after the 25th fraction and genitourinary toxicity grades after the 25th fraction, were found. The pretreatment IL-6 concentrations and TGF-ß1 concentrations after the 25th fraction were positively correlated with maximum genitourinary toxicity grades. The IL-6 levels after the 25th fraction were positively associated with genitourinary toxicity grades after this fraction. The pretreatment IL-6 concentrations were significantly positively correlated with maximum fatigue scores. The significant positive correlation between IL-6 concentrations and fatigue scores after the 25th fraction was determined. The positive correlations between IL-6 and TGF-ß1 concentrations measured after the 25th fraction and maximum fatigue scores were observed. CONCLUSIONS: Our results suggest that serum levels of IL-6 and TGF-ß1 might influence the severity of acute genitourinary radiotoxicity and fatigue in patients with prostate cancer. Combining clinical parameters and circulating cytokine levels might be useful for the prediction of adverse reactions to radiotherapy.

INTRODUCTION: The association between the expression of HIF-1α in the laryngeal carcinoma and the prognosis of disease is quite well documented, but the significance of HIF-1α C1772T polymorphism and its relation to disease phenotype have to be clarified. The aim of this study was to investigate the influence of C1772T polymorphism on the clinical-pathological characteristics and disease-free survival after initial surgical treatment of patients with laryngeal carcinoma. MATERIALS AND METHODS: The prospective cohort study included 65 patients with laryngeal carcinoma. Two representative tumor tissue specimens were taken in each patient during surgery; 1 specimen was used to asses HIF-1α C1772T polymorphism and the other 1 to determine the immunohistochemical expression of HIF-1α, VEGF, as well as CD 34 proteins. The comparison of polymorphism frequency between study and control population was conducted by collecting a 5 mL of peripheral venous blood samples in each subject. RESULTS: Clinicopathological characteristics of laryngeal carcinoma didn't affect the expression of hypoxia-related biomarkers, such as HIF-1α, VEGF or MVD. The statistically significant association between HIF-1α and VEGF expression was found (P = .034), but not between HIF-1α expression and MVD value (P = .696). The expression of HIF-1α was significantly higher among CT heterozygotes (P = .029). We found a significantly more recurrence among CT heterozygotes compared with patients with CC homozygous alleles (57.10% and 24.30%, respectively; P = .007). Patients with C1772T polymorphic variants had significantly worse disease-free survival compared with patients without polymorphism (Log-rank test, P = .007). CONCLUSION: HIF-1α C1772T polymorphism was significantly associated with worse disease-free survival which nominates it as a predictor of laryngeal carcinoma relapse. The preoperative assessment of hypoxia-related biomarkers should be used in everyday practice in order to determine the treatment modalities for laryngeal carcinoma.

We evaluated factors influencing long-term health-related quality of life (HRQoL) after excisional treatments of low- and high grade squamous intraepithelial cervical lesions (SIL) in three groups of women (n = 160): nulliparas interested in reproduction (A), parous women interested in reproduction (B) and women without pregnancy desire (C). The HRQoL was assessed using the disease-specific FACIT-CD and the generic SF36v2 questionnaires. Anxiety and depression were evaluated by Beck's inventories. After median follow-up of 5 (2-18) years, FACIT-CD total score and the score for Emotional Well-Being (EWB) were significantly lower in group A. The total, EWB and REL (Relationships) scores of FACIT-CD were the highest in group B. Women operated for HSIL demonstrated lower REL quality in comparison to those with LSIL. Neither SF36v2 nor FACIT-CD total scores differed in relation to SIL grade or type of excision. 'SF36v2 Mental Component Summary Score' and 'being parous and interested in fertility' were independent predictors of disease-specific FACIT-CD score.Impact StatementWhat is already known on this subject? Long-term consequences of excisional treatments for cervical dysplasia on health-related quality of life (HRQoL) are not well reported.What do the results of this study add? Our study provides data on HRQoL in women treated with large loop excision of the transformation zone (LLETZ) or cold knife conization (CKC) obtained during the longest (median 5 years) follow-up as reported to date. We were able to show that having children and planning further pregnancies positively influenced HRQoL in these patients. In addition, we identified nulliparas with pregnancy desire as psychologically the most vulnerable group within the studied cohort.What are the implications of these findings for clinical practice and/or further research? Even several years after LLETZ or CKC, women may suffer from impaired Emotional Well-Being and reduced HRQoL. Awareness and assessment of these long-term consequences should be part of surveillance after excisional treatments for cervical dysplasia.

BACKGROUND: Traditional face-to-face clinical learning became problematic for final year dental students during the COVID-19 pandemic. Distance-learning may help mitigate the immediate impact of dental school closures. Integrating e-learning technologies into the learning process helps bridge the gap between pre-clinical and clinical training. Simulation allows students to repeat procedures until they demonstrate acceptable levels of skill. This study aimed to determine the effectiveness of a serious game as an additional teaching tool during the COVID-19 era to improve dental students' local anaesthesia administration technique and confidence. METHODS: This study applied a simulation-based serious game as an additional learning tool for training and educating dental students in local anaesthesia. Students used a mobile simulator in Serbian for 10 days from their homes. To evaluate the learning process, the students completed a post-training questionnaire. RESULTS: All respondents felt comfortable using the simulator. Over 90% of respondents believed that the application facilitated the learning process and had advantages in terms of accessibility and ease of use. Also, students found augmented reality (AR) technology particularly interesting to use. The use of a mobile simulator designed as a 3D and AR environment allows for simpler localisation and identification of anatomical structures and reference points, which is a good base for clinical practice. CONCLUSION: Serious games of local anaesthesia procedures as an additional e-learning tool during the COVID-19 era could improve students' knowledge and skills.

Background and Objectives: In chronic kidney obstruction, the severity of tubulointerstitial damage correlates best with the loss of kidney function and the risk for progression to end-stage kidney disease. The present study aimed to investigate the potential clinical significance of serum uromodulin (sUmod) as a marker of early kidney disfunction in patient with obstructive nephropathy (ON). Materials and Methods: Serum Umod level was measured by sensitive ELISA method in 57 adult patients with obstructive nephropathy and 25 healthy subjects in control group. Kidney function was precisely evaluated via measured glomerular filtration rate (mGFR) (renal clearance of 99 mTc-diethylenetriamine penta-acetic acid), effective renal plasma flow (ERPF) and Cystatin C level. Recruited patients were divided into subgroups based on the mGFR: group IGFR ≤ 60 mL/min/1.73 m2 (N = 31), group IIGFR > 60 mL/min/1.73 m2 (N = 26). Results: A significantly lower level of serum uromodulin was measured in patients with ON (50.2 ± 26.3 ng/mL) compared to the control group (78.3 ± 24.5 ng/mL) (p < 0.001). The mean level of serum Umod was significantly different between group I (30.5 ng/mL ± 11.1) and group II (73.6 ng/mL ± 18.6) (p < 0.001), but not between group II (73.6 ng/mL ± 18.6) and control group (78.3 ± 24.5 ng/mL). There was a positive correlation between sUmod and mGFR (R = 0.757, p < 0.001) and ERPF (R = 0.572 p < 0.001), with lower sUmod levels in patients with impaired renal function. An inverse relationship was detected between sUmod and filtration markerscystatin C (R = −0.625, p < 0.001), creatinine, urea and uric acid. ROC analysis of sUmod to differentiate between ON patients with GFR below 60 mL/min/1.73 m2 and above 60 mL/min/1.73 m2 resulted in AUC of 0.98 (p < 0.001, 95% CI 0.922 vs. 0.998) at a cut-off value of 46 ng/mL (specificity 96.8%, sensitivity 92.2%). Conclusions: The significant correlation of sUmod with kidney function parameters may imply potential clinical significance as a noninvasive biomarker of early kidney disfunction in obstructive nephropathy.

Background and Objectives: The aim of the study was to evaluate vision-related quality of life (VR-QOL) and treatment satisfaction (TS) in patients with diabetic retinopathy treated with panretinal photocoagulation (PRP). Material and Methods: The panel study included 95 patients who underwent PRP for diabetic retinopathy. Eligible patients with no history of previous PRP were interviewer-administered the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and Retinopathy Treatment Satisfaction Questionnaire (RetTSQ) beforehandand one month after the last session of laser application. The study was conducted between June 2017 and June 2019 at tertiary care center in Serbia, Belgrade. We assessed pre- to post-PRP values of the composite score and subscale scores of VFQ-25 and RetTSQ, using a paired samples t-test. Univariate logistic regression was used to analyze the relationship between binary outcomes and potential predictors. Multivariate regression included predictors from univariate analyses that were statistically significant. Results: The mean VFQ-25 composite score was 65.4 ± 17.4 before and 63.3 ± 19.5 after PRP (p = 0.045). Subscale analysis showed that two of the 11 items achieved a significant decrease after laser application (general vision and dependency). The mean RetTSQ score at baseline was 60.0 ± 11.8 and at the exit visit was 60.3 ± 12.3 (p = 0.858). Sub-scale analysis showed significant deterioration for five of the 13 items. Multivariate logistic regression found that significant predictor of VFQ-25 composite score reduction was fewer laser burns (p = 0.002) while significant predictor of RetTSQ total score reduction was presence of hyperlipidaemia (p = 0.021). Conclusion: The use of vision-related quality of life and treatment satisfaction questionnaires in conjunction with clinical examination, appears to provide a more comprehensive overview of an individual's daily well-being following PRP. Laser treatment for diabetic retinopathy leads to deterioration of some of the patients' perceived VR-QOL and TS. Health-care providers should inform patients about their treatment options and together decide which therapeutic method is best for them.

AIM: The aim of the study was to examine the effectiveness of intraoral thermoformed splint with a magnet device over a period of 3 months, that is, to assess acceptability of this method of treatment using both objective and self-reported measures. MATERIALS AND METHODS: This study was designed as a prospective clinical pilot trial. 22 patients with xerostomia and hyposalivation were included. Xerostomia was assessed using a 4-question xerostomia questionnaire score and a test for unstimulated salivary flow rates. Evaluations were performed before the treatment and 3 months after the treatment using a thermoformed splint with a magnet device. RESULTS: There was a significant reduction in subjective symptoms after using a thermoformed splint with a magnet device for 3 months. For all 4 scored items, there was a statistically significant difference (P < .001) in median VAS scores before and 3 months after treatment. There was also a statistically significant difference in USFR before (0,15 ± 0,04 ml/min) and after treatment (0,24 ± 0,03 mL/min). CONCLUSION: Our findings indicate that the use of this device alleviated oral dryness and stimulated the function of the submandibular salivary gland. An intraoral thermoformed splint with a magnet device is safe, physiologically indifferent, useful, and effective in treating xerostomia and hyposalivation.

OBJECTIVE: To perform a follow-up study of the quality of life in patients with epilepsy in the era of the COVID-19 crisis. METHODS: Two months before the first case of the COVID-19 in Serbia, we obtained the Serbian Version of Quality of Life Inventory for Epilepsy 31 (SVQOLIE-31) and Neurological Disorders Depression Inventory for Epilepsy scores (SVNDDI-E) for another study. We retested the same patients one year after in COVID-19 pandemic. In addition to SVQOLIE-31, and SVNDDI-E we used a generic questionnaire compiled from items related to the COVID-19. RESULTS: We retested 97 out of 118 patients (82.2%) for the follow-up analysis. The average age was 36.1⯱â¯12.2 (range: 18-69), and 49 were women (50.5%). The median duration of epilepsy was 13â¯years (range: 1.5-48). The structural etiology of epilepsy was noted in 41 (42.3%), unknown etiology in 41 (42.3%), and genetic etiology in 15 (15.4%) patients. Fewer patients (27.8%) experienced at least one seizure three months before follow-up testing when compared to patients who experienced at least one seizure three months in initial testing (36.0%) (pâ¯=â¯0.15). All patients reported full compliance with anti-seizure medication in the follow-up. The SVQOLIE-31 score during the COVID-19 pandemic visit (64.5⯱â¯14.6) was significantly lower than the SVQOLIE-31 score before the pandemic (pâ¯<â¯0.001). The SVNDDI-E score during the COVID-19 pandemic (10.5⯱â¯3.5) was significantly higher than the SVNDDI-E score before it (pâ¯<â¯0.001). Multiple linear regression analyses revealed fear of seizures, and fear of a reduction in household income, significantly associated with SVQOLIE-31 and SVNDDI-E overall score. These variables accounted for 66% and 27% of the variance of SVQOLIE-31 and SVNDDI-E overall score. SIGNIFICANCE: Lower quality of life, higher prevalence of depression, healthcare availability issues, and perceived fears during pandemic all suggest COVID-19 has negatively impacted lives of patients with epilepsy.

We evaluated coagulation abnormalities via traditional tests and rotational thromboelastometry (ROTEM) in a group of 94 patients with confirmed SARS-CoV-2 infection and different severity of pneumonia (34 moderate, 25 severe, 35 critical) with the hypothesis that ROTEM parameters differed by coronavirus disease 2019 (COVID-19) severity. Shorter than normal clotting time (CT) and higher than normal maximum clot firmness (MCF) in extrinsic rotational thromboelastometry (EXTEM) and fibrinogen rotational thromboelastometry (FIBTEM), shorter than normal EXTEM clot formation time (CFT), and higher than normal α-angle were classified as markers of hypercoagulable state. Increment in the number of patients with ≥2 hypercoagulable parameters, higher EXTEM (P = .0001), FIBTEM MCF (P = .0001) and maximum lysis decrement (P = .002) with increment in disease severity was observed (P = .0001). Significant positive correlations between IL6 and CT EXTEM (P = .003), MCF EXTEM (P = .033), MCF FIBTEM (P = .01), and negative with ML EXTEM (P = .006) were seen. Our findings based on analysis of different disease severity groups confirmed that a hypercoagulable ROTEM pattern characterized by clot formation acceleration, high clot strength, and reduced fibrinolysis was more frequent in advanced disease groups and patients with high IL6. These results supported the need for different thromboprophylaxis approaches for different severity groups.

PURPOSE: Otitis media with effusion (OME) associated with Samter's triad (ST) is a difficult entity to treat. The aim of study was an investigation of the middle ear and nasal production of inflammatory mediators (IM) in patients with ST and analysing differences between them and controls. METHODS: Prospective case-control study. Nineteen patients with OME (five had allergic rhinitis, four had nasopharyngeal lymphoid hyperplasia, five had no evident sino-nasopharyngeal disease and five had confirmed ST) and 15 healthy participants were included. The concentrations of IM interleukin-1 beta (IL-1ß), interferon-alpha 2 (IFN-α2), interferon-gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), monocyte chemoattractant protein-1 (MCP-1), IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-18, IL-23 and IL-33 were measured in nasal and middle ear secretions. RESULTS: There was a difference that was close to a level of statistical significance only for IL-1ß levels in middle ear fluid (p = 0.052) between the ST subgroup and the other patients with OME. Also, we found a significant difference for IL-23 in nasal secretions between these subgroups (p = 0.040), whereas the difference in nasal fluid IL-33 was close to a level of statistical significance (p = 0.052). There was a significant difference in nasal concentrations of IL-1ß, IFN-α2, MCP-1, IL-8, IL-18 and IL-33 (p < 0.001, p = 0.005, p = 0.008, p = 0.011, p = 0.011 and p = 0.011, respectively) between the OME group and the healthy subjects. There were significant positive correlations between concentrations of IL-1ß, IFN-α2, IFN-γ, TNF-α, MCP-1, IL-17A, IL-18 and IL-33 (p < 0.001, p < 0.001, p = 0.002, p = 0.028, p < 0.001, p < 0.001, p < 0.001 and p < 0.001, respectively) in nasal and middle ear secretions. CONCLUSION: This preliminary report showed some differences in IM production between the patients with OME associated with ST and those without it. Our results suggest a uniformity of the production of nasal and middle ear IM and supported the concept of a united airway respiratory disease.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease which is characterized by extremely complex pathogenetic mechanisms and multifactorial etiology. Some of the many pathophysiological mechanisms involved in the development of NAFLD include oxidative stress, impaired mitochondrial metabolism, inflammation, gut microbiota, and interaction between the brain-liver-axis and the regulation of hepatic lipid metabolism. The new therapeutic approaches in the treatment of NAFLD are targeting some of these milestones along the pathophysiological pathway and include drugs like agonists of peroxisome proliferator-activated receptors (PPARs), glucagon-like peptide-1 (GLP-1) agonists, sodium/glucose transport protein 2 (SGLT2) inhibitors, farnesoid X receptor (FXR) agonists, probiotics, and symbiotics. Further efforts in biomedical sciences should focus on the investigation of the relationship between the microbiome, liver metabolism, and response to inflammation, systemic consequences of metabolic syndrome.

OBJECTIVE: Many studies have reported insufficient support from surgical services, resulting in nephrologists creating arteriovenous fistulas in many centers. The aim of this study was to compare risk factors of arteriovenous fistula dysfunction in patients whose fistulas were created by nephrologists versus vascular surgeons. METHODS: This was a retrospective, analytical study of interventions by nephrologists and vascular surgeons during a period of 15 years. Out of a total of 1,048 fistulas, 764 (72.9%) were created by nephrologists patients, while vascular surgeons were responsible for 284 (27.1%) fistulae. Laboratory, demographic, and clinical parameters which might affect functioning of these arteriovenous fistulae were analyzed. RESULTS: Patients whose arteriovenous fistula was formed by nephrologists differed significantly from those created by vascular surgeons in relation to the preventive character of the arteriovenous fistula (p = 0.011), lumen of the vein (p < 0.001) and systolic blood pressure (p = 0.047). Multivariate logistic regression of arteriovenous fistula dysfunction showed that risk factors were female gender (odds ratio [OR] = 1.56, 95% CI 1.16-2.07), whether the fistulae were created by vascular surgeons or nephrologists (OR = 1.38; 95% CI 1.01-1.89) and the site of the arteriovenous fistula (OR = 0.64; 95% CI 0.48-0.85). CONCLUSIONS: Arteriovenous fistulae created by vascular surgeons, female gender, and the location are risk factors of dysfunction.

Reports highlighting the problems with the standard practice of using bar graphs to show continuous data have prompted many journals to adopt new visualization policies. These policies encourage authors to avoid bar graphs and use graphics that show the data distribution; however, they provide little guidance on how to effectively display data. We conducted a systematic review of studies published in top peripheral vascular disease journals to determine what types of figures are used, and to assess the prevalence of suboptimal data visualization practices. Among papers with data figures, 47.7% of papers used bar graphs to present continuous data. This primer provides a detailed overview of strategies for addressing this issue by (1) outlining strategies for selecting the correct type of figure depending on the study design, sample size, and the type of variable; (2) examining techniques for making effective dot plots, box plots, and violin plots; and (3) illustrating how to avoid sending mixed messages by aligning the figure structure with the study design and statistical analysis. We also present solutions to other common problems identified in the systematic review. Resources include a list of free tools and templates that authors can use to create more informative figures and an online simulator that illustrates why summary statistics are meaningful only when there are enough data to summarize. Last, we consider steps that investigators can take to improve figures in the scientific literature.
