Abstract
OBJECTIVE Cardiopulmonary resuscitation (CPR) is a vital skill that can improve the outcome of patients with sudden cardiac arrest. To raise awareness about CPR some countries have introduced an obligatory First Aid Course (FAC), usually done parallelly to a driver's license (DL). While expected of doctors to know CPR, the curriculum of some medical schools does not seem to have enforced measures to improve that knowledge. The aim was to have students self-evaluate their current knowledge of CPR, comparing it before university and whether it improved during their studies. SUBJECTS AND METHODS A cross-sectional study was conducted in October 2020 using an anonymous questionnaire among students at the Faculty of Medicine in Belgrade (studies in English). RESULTS A total of 172 (66.7%) students possessed a DL, of which 39.8% felt they were ready, 45.8% felt neutral, and 14.4% felt unable to perform CPR. The total number of students that completed a FAC during their studies was 165. Analysis was performed on the ability assessment data after the first FAC during studies, comparing it to FAC for DL and assessments at the end of studies. No statistically significant difference was observed in the level of self-reported ability to perform CPR, while a statistically significant difference was found in ability assessments when comparing only the FAC for the DL, and the one after the first FAC during medical studies, with students feeling more prepared after the FAC for DL. Across the sample, 90.2% of the students wished they had more CPR training during their medical studies. CONCLUSIONS From this study, it may conclude that students wish and need more CPR training in their curriculum.

Abstract
PURPOSE Patients undergoing carotid endarterectomy (CEA) or carotid artery stenting (CAS) are at substantially increased risk of short-term and long-term cardiac complications. Still, the role of perioperative troponin in predicting cardiac events remains unclear. The objective was to systematically summarize the existing evidence on the topic and provide directions for further research. MATERIALS AND METHODS Studies that examined perioperative troponin values and its association with myocardial injury, and/or myocardial infarction (MI), and/or major adverse cardiac events (MACE) and postoperative mortality in exclusively CEA/CAS patients, published in English until March 15, 2022, were retrieved through a systematic search of MEDLINE and Web of Science. The study selection process was independently performed by 2 authors, while the third researcher resolved disagreements. RESULTS Four studies with 885 participants met the inclusion criteria. Age, chronic kidney disease, presentation of carotid disease, type of closure (primary closure/venous patch/Dacron/polytetrafluoroethylene patch), coronary artery disease, chronic heart failure, and the long-term use of calcium channel blockers represent risk factors for troponin elevation, which occurred in 11% to 15.3%. Myocardial infarction and MACE occurred in 23.5% to 40%, that is, 26.5% of patients with troponin elevation, respectively, during the first 30 postoperative days. Elevated postoperative troponin levels were significantly associated with adverse cardiac events during the long-term surveillance period. The rates of cardiac-related and all-cause mortality were higher in patients with postoperative troponin elevation. CONCLUSION Troponin measurement could be helpful in the prediction of adverse cardiac events. The predictive role of preoperative troponin, the patient population in whom routine troponin sampling should be used, and a comparison of different treatment methods/anesthesia techniques in carotid patients should be further examined. CLINICAL IMPACT The present scoping review critically appraises the extent and nature of the existing literature data on the predictive value of troponin on the occurrence of cardiac complications in patients undergoing CEA and CAS. In particular, it provides clinicians with essential insights by systematically summarizing the core evidence and identifying knowledge gaps that may direct future research. This, in turn, may significantly alter the current clinical practice and perhaps even reduce the incidence of cardiac complications in patients undergoing CEA/CAS.

Translocator Protein Modulation by 4'-Chlorodiazepam and NO Synthase Inhibition Affect Cardiac Oxidative Stress, Cardiometabolic and Inflammatory Markers in Isoprenaline-Induced Rat Myocardial Infarction. Int J Mol Sci 2021; 22:2867. [PMID: 33799869 PMCID: PMC8000569 DOI: 10.3390/ijms22062867] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 03/05/2021] [Accepted: 03/08/2021] [Indexed: 11/17/2022] Open
Abstract
The possible cardioprotective effects of translocator protein (TSPO) modulation with its ligand 4'-Chlorodiazepam (4'-ClDzp) in isoprenaline (ISO)-induced rat myocardial infarction (MI) were evaluated, alone or in the presence of L-NAME. Wistar albino male rats (b.w. 200-250 g, age 6-8 weeks) were divided into 4 groups (10 per group, total number N = 40), and certain substances were applied: 1. ISO 85 mg/kg b.w. (twice), 2. ISO 85 mg/kg b.w. (twice) + L-NAME 50 mg/kg b.w., 3. ISO 85 mg/kg b.w. (twice) + 4'-ClDzp 0.5 mg/kg b.w., 4. ISO 85 mg/kg b.w. (twice) + 4'-ClDzp 0.5 mg/kg b.w. + L-NAME 50 mg/kg b.w. Blood and cardiac tissue were sampled for myocardial injury and other biochemical markers, cardiac oxidative stress, and for histopathological evaluation. The reduction of serum levels of high-sensitive cardiac troponin T hs cTnT and tumor necrosis factor alpha (TNF-α), then significantly decreased levels of serum homocysteine Hcy, urea, and creatinine, and decreased levels of myocardial injury enzymes activities superoxide dismutase (SOD) and glutathione peroxidase (GPx) as well as lower grades of cardiac ischemic changes were demonstrated in ISO-induced MI treated with 4'-ClDzp. It has been detected that co-treatment with 4'-ClDzp + L-NAME changed the number of registered parameters in comparison to 4'-ClDzp group, indicating that NO (nitric oxide) should be important in the effects of 4'-ClDzp.

Abstract
This study aimed to investigate the effects of propofol through evaluating its interaction with nitric oxide (NO), hydrogen sulfide (H2S), and carbon monoxide (CO). Wistar male rats were divided in 4 groups: (1) bolus injection of propofol (1% 10 mg/mL, 100 mg/kg bw, i.p.); (2) Nω-nitro-l-arginine methyl ester (L-NAME; NO synthase inhibitor, 60 mg/kg bw, i.p.) + bolus injection of propofol (1% 10 mg/mL, 100 mg/kg bw, i.p.); (3) DL-propargylglycine (DL-PAG; H2S synthase inhibitor, 50 mg/kg bw, i.p.) + bolus injection of propofol (1% 10 mg/mL, 100 mg/kg bw, i.p.); (4) zinc protoporphyrin IX (ZnPPIX; CO synthase inhibitor, 50 μmol/kg bw, i.p.) + bolus injection of propofol (1% 10 mg/mL, 100 mg/kg bw, i.p.). Increased levels of albumins, low-density lipoproteins, alkaline phosphatase, amylase, high-sensitivity Troponin T, and fibrinogen were found in L-NAME + propofol group. Platelet crit, platelet count, total cholesterol, and high-density lipoproteins were elevated in ZnPPIX + propofol group. Hydrogen peroxide was increased in all groups treated with gasotransmitters inhibitors. Reduced glutathione was reduced in all groups, superoxide dismutase activity only in L-NAME + propofol. The effect of propofol on various biochemical, haematological, and oxidative stress markers may be at least in part mediated through interaction with 3 estimated gasotransmitters.

Abstract
It has been assumed that the cardioprotective effects of propofol are due to its non-anesthetic pleiotropic cardiac and vasodilator effects, in which gasotransmitters (NO, H2S, and CO) as well as calcium influx could be involved. The study on isolated rat heart was performed using 4 experimental groups (n = 7 in each): (1) bolus injection of propofol (100 mg/kg body mass, i.p.); (2) L-NAME (NO synthase inhibitor, 60 mg/kg body mass, i.p.) + propofol; (3) DL-PAG (H2S synthase inhibitor, 50 mg/kg body mass, i.p.) + propofol; (4) ZnPPIX (CO synthase inhibitor, 50 μmol/kg body mass, i.p.) + propofol. Before and after the verapamil (3 μmol/L) administration, cardiodynamic parameters were recorded (dp/dtmax, dp/dtmin, systolic left ventricular pressure, diastolic left ventricular pressure, heart rate, coronary flow), as well as coronary and cardiac oxidative stress parameters. The results showed significant increases of diastolic left ventricular pressure following NO and CO inhibition, but also increases of coronary flow following H2S and CO inhibition. Following verapamil administration, significant decreases of dp/dtmax were noted after NO and CO inhibition, then increase of diastolic left ventricular pressure following CO inhibition, and increase of coronary flow following NO, H2S, or CO inhibition. Oxidative stress markers were increased but catalase activity was significantly decreased in cardiac tissue. Gasotransmitters and calcium influx are involved in pleiotropic cardiovascular effects of propofol in male Wistar rats.

Abstract
BACKGROUND Constitutive activation of STAT3 have been shown in several tumor types including breast cancer. We investigate STAT3 expresion as possible molecular marker for breast cancer early detection, as well as prognostic factor for determination of tumor agressiveness. METHODS In this study we measure p(Y705)STAT3 expression in tumor and adjacent tissue of breast cancer patients by Western blot. For relapse-free survival (RFS) and overall survival (OS) we used Log-Rank test. RESULTS We show that average expression of p (Y705) STAT3 in tumor tissue is higher compared to adjacent tissue. Moreover, we found that patients with HER2 positive receptors had significantly higher pSTAT3 expression compared to HER2 negative patients. We showed that patients with high mammographic density had significantly higher tumor expression of pSTAT3 compared to patients with low mammographic density. Also, we show that pSTAT3 expression correlates with longer RFS in the entire group of patients, as well as in the group of ER positive, in lymph node positive and in older group of breast cancer patients (with age over 50). Furthermore, in the entire group of patients, in ER positive, in lymph node positive and in older group of patient, high expression of pSTAT3 showed a better survival than low expression of pSTAT3. CONCLUSION Considering that the expression of pSTAT3 is associated with longer RFS and survival, it can be used as prognostic tools for determination of group of breast cancer patients with low-risk.

Abstract
BACKGROUND/AIM Intraabdominal hypertension (IAH) is a common clinical finding in patients with acute pancreatitis and is associated with poor prognosis. This study aimed to determine the impact of intraabdominal pressure (IAP) on the mortality rate in patients with acute pancreatitis in an intensive care unit. MATERIALS AND METHODS A total of 50 patients with acute pancreatitis were included in this prospective cohort study. Based on the obtained values of IAP, the patients were divided into two groups: those with normal IAP (n = 14) and increased IAP (n = 36). Mean values of IAP were compared with examined variables. RESULTS The mortality rate of the study group was 40%. Comparing the IAP and treatment outcomes, it was proved that there were statistically highly significant differences (P = 0.012). Increasing the value of IAP increased the mortality rate. Deceased patients in the IAH group had greater statistical significance of APACHE II score (P = 0.016), abdominal perfusion pressure (P = 0.048), lactate (P = 0.049), hematocrit (P = 0.039), Ranson's criteria on admission (P = 0.017), Ranson's criteria after 48 h (P = 0.010), Sequential Organ Failure Assessment score (P = 0.014), and body mass index (P = 0.012) compared to the surviving patients. CONCLUSION IAP has an impact on the increase of mortality rates in patients with acute pancreatitis.

Abstract
Sepsis-associated acute kidney injury (SA-AKI) severely impacts morbidity and mortality in surgical patients with sepsis. Matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) have an important role in pathophysiology of sepsis but they have been unexplored in SA-AKI. We aimed to investigate the role of MMP-9 and TIMP-1 in septic surgical patients with SA-AKI and to evaluate them as diagnostic biomarkers of SA-AKI. This prospective observational study compared 53 major abdominal surgery patients with sepsis divided into SA-AKI (n = 37) and non-SA-AKI (n =16) group to 50 controls without sepsis matched by age, gender, comorbidities and type of surgery. Blood and urine samples from septic patients were collected on admission to ICU and 24, 48, 72 and 96 h later and once from the controls. The levels of MMP-9, TIMP-1, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1, urea and creatinine were measured. MMP-9/TIMP-1 ratio and disease severity scores, such as Sequential Organ Failure Assessment (SOFA), were calculated. Septic patients with SA-AKI had higher serum TIMP-1 levels and lower serum MMP-9 levels and lower MMP-9/TIMP ratio, compared to septic patients without SA-AKI and controls. The levels of these biomarkers did not change significantly over time. MMP-9, TIMP-1 and MMP-9/TIMP-1 ratio correlated with urea, creatinine, NGAL, and SOFA scores. Moreover, using the area under ROC curve, we showed that TIMP-1 and MMP-9/TIMP-1 ratio, but not MMP-9, were good diagnostic biomarkers of SA-AKI. We report for the first time the potential diagnostic value of TIMP-1 and MMP-9/TIMP-1 ratio in SA-AKI.

Abstract
Human epidermal growth factor receptor 2 (HER2)-positive breast cancers represent a highly aggressive breast cancer subtype and are associated with a worse prognosis. This study was designed to investigate the mammography finding of HER2-positive breast cancer and to compare the results with the characteristics of HER2-negative breast cancer patients. From January 2010 to October 2011, mammography findings of 65 patients with pathologically confirmed HER2-positive breast cancers (n = 22) or HER2-negative breast cancers (n = 43) were retrospectively reviewed. The authors also reviewed pathological reports for information on the histological type and differentiation grade. Among the two types of breast cancer patients, estrogen receptor-negative/PR-negative/HER2-positive breast cancer patients most commonly had associated calcifications (18 of 22) on mammography. On mammography, cases with a cluster of calcifications usually were presented as pleomorphic calcifications (12 of 20) and branching calcifications (4 of 20). Patients with HER2-positive breast cancers showed a histological grade II. HER2-positive breast cancer patients usually had ductal invasive carcinoma (17 of 22). Moreover, postmenopausal patients showed a significantly higher frequency of HER2-positive tumours. Our results suggest that the imaging findings might be useful in diagnosing HER2-positive breast cancer patients.

Abstract
The purpose of this study was to investigate left ventricular (LV) mechanics in hypertensive patients by 2- and 3-dimensional (3D) speckle tracking imaging, and determine the relation between the LV mechanics and functional capacity in this population. This cross-sectional study included 51 recently diagnosed, untreated, hypertensive patients, 49 treated subjects with well-controlled arterial hypertension, 52 treated participants with uncontrolled hypertension, and 50 controls adjusted by gender and age. All the subjects underwent 24-hour blood pressure monitoring, complete 2-dimensional and 3D examination, and cardiopulmonary exercise testing. 3D global longitudinal, circumferential, radial, and area strains were similar between the control group and well-controlled hypertensive patients but significantly decreased in comparison with patients with untreated or inadequately controlled hypertension. Similar findings were obtained for LV torsion and twist rate, whereas LV untwisting rate significantly deteriorated from the controls, across the well-controlled group, to the patients with untreated or uncontrolled hypertension. Peak oxygen uptake was significantly lower in the patients with untreated and uncontrolled hypertension than in the controls and the well-treated hypertensive patients. Peak oxygen uptake was independently associated with LV untwisting rate (β = 0.28, p = 0.03), 3D LV ejection fraction (β = 0.31, p = 0.024), and 3D global longitudinal strain (β = 0.26, p = 0.037) in the whole hypertensive population in our study. In conclusion, LV mechanics and functional capacity are significantly impaired in the patients with uncontrolled and untreated hypertension in comparison with the controls and the well-controlled hypertensive patients. Functional capacity is independently associated with 3D global longitudinal strain, LV untwisting rate, and 3D LV ejection fraction.

Abstract
BACKGROUND Stenting of malignant hilar strictures remains a standard endoscopic treatment in patients with unresectable tumors. The aim of this two-center prospective study was to compare unilateral versus bilateral drainage in hilar malignant stenosis Bismuth-Corlette type II. METHODS During a 3-year period, a total of 49 patients with hilar tumors (Bismuth-Corlette type II) were referred for endoscopic treatment, following the criteria of unresectability. Ultrasound, computed tomography scan and magnetic resonance cholangiopancreatography (MRCP) were previously performed in all patients in order to facilitate endoscopic retrograde cholangiopancreatography (ERCP). The stricture was first passed by the hydrophilic guide-wire and then contrast medium was injected. Mechanical bile duct dilation was performed, followed by plastic stent placement only in the liver lobe which was previously opacified. The procedures were performed under conscious sedation. The patients were followed up for the next 12 months with a stent exchange every 3 months. Primary outcome was assessed by patient survival in the first 12 months after the procedure. RESULTS All 49 patients were treated with ERCP while 39 (79.59%) had successful stent placement. Among these, 32 had hilar cholangiocarcinoma (82%) and 7 (18%) had gallbladder cancer. Two groups of patients had Bismuth II strictures: A, 21 patients (54%) with unilateral contrast injection and drainage, and B, 18 (46%) with bilateral contrast injection and drainage. A total of 57 plastic stents were used (10 Fr, 89%; 11.5 Fr, 11%). Group B showed a lower bilirubin level 7 days after the procedure (P=0.008). Early complications were cholangitis (3 patients, 2 in group A and 1 in group B) and acute pancreatitis (2 patients, 1 each in A and B) with no statistical difference between the groups. Late complications were stent migration (5 patients, 1 in A and 4 in B) and stent clogging (6 patients, 2 in A and 4 in B) showing a significant difference between the groups (P<0.01). The first stent replacement after 3 months was successful in 87% of patients (four died due to disease progression and one due to cardiopulmonary insufficiency) showing no statistical difference between the groups. At 6 months follow-up, 72% patients survived, with no statistical difference between the groups. A final follow-up (12 months) showed the survival rate of 18% (4 patients from group A and 3 from group B) (P>0.05). CONCLUSIONS A minimally invasive approach, based on the criterion that every bile duct being opacified needs to be drained, is associated with a lower incidence of early complications. Considering that the clinical outcome measured by bilirubin level was lower in patients with bilateral drainage 7 days after the procedure, we assumed that drainage of 50% or more of the liver volume leads to sufficient drainage effectiveness.

Abstract
The administration of glucose-insulin-potassium (GIK) solution has beeen shown to exert cardioprotective and immunomodulatory properties in coronary disease. 49 patients (pts.) for coronary surgery were randomly assigned to receive high-dose GIK treatment (30% glucose, insulin 2 IU.kg(-1).l(-1) and K(+) 80 mmo/l solution; 1 ml/kg/h); low-dose GIK treatment (10% glucose, insulin 32 IU l(-1) and K(+) 80 mmol/l solution; 1 ml/kg/h) or control treatment (Ringer solution 1 ml/kg/h). Haemodynamic measurements were done for four time points: T1 - after induction of anaesthesia; T2 - after the operation; T3 - 6 h after the operation and T4 - 24 h after the operation. Significant recovery of cardiac function was evident in high-dose GIK (H-GIK) and low-dose GIK (L-GIK) groups after 24 h (cardiac index improved considerably (p = 0.0002)), with a statistically significant difference between the groups (p = 0.005). LVSWI covariated with PCWP, improved over time in group H-GIK (p = 0.0008) and between the groups (p = 0.046). Oxygen supply-consumption ratio evidently improved in the GIK groups, while inotropic drug support was used in 5.5% pts. in group H-GIK vs. 13% in group L-GIK and 31% pts. in control (C) group. Glucose-insulin treatment has a potential cardioprotective effect in coronary surgery. The effect is independent of the glucose-insulin concentration and amount.
