Abstract
Abstract
Background
Pulmonary embolism (PE) can lead to multi-organ damage including an acute renal dysfunction which is associated with adverse events and high long-term mortality rate.
Purpose
The aim of our study was to investigate the predictive role of renal dysfunction on intrahospital mortality risk in patients hospitalized due to PE. The study was performed in intensive care units of six university hospitals.
Methods
The prospective cohort study comprised 665 consecutive patients with acute PE which was confirmed using MDCT. All patients underwent echocardiography examination on admission and blood samples were collected for troponin I (TnI), B-type natriuretic peptide (BNP) and routine laboratory analyses.
Results
Based on estimated glomerular filtration rate (GFR), patients were divided into three groups: first with the GFR <30ml/min, second with GFR 30–60 ml/min, and third with GFR >60 ml/min. During hospitalization in the first group the overall incidence of death was recorded in 28 (45.9%), in the second in 42 (18.9%), and in the third in 30 (7.9%) patients (p<0.0001). Pulmonary embolism as a cause of death was recorded in the first group in 18 (29.5%) patients, in the second in 25 (11.3%) and in the third in 17 (4.5%) patients (p<0.0001). Fatal bleeding was recorded in the first group in 1 (1.6%), in the second in 1 (0.5%) and in the third group in 3 (0.8%) patients (p<0.05). There were no significant differences regarding major bleeding frequency among the groups. Multivariate analysis showed that age, comorbidities, hemodynamic status, TnI, and GFR were strongly associated with an overall mortality rate and with death due to PE, while the use of anticoagulation therapy influenced the fatal bleeding rate. After controlling for age, we found that GFR on admission had a significant effect on in-hospital survival. Compared with patients in the third group, those from the second group had more than 2 fold increased mortality risk [OR 2.17 (CI 1.301–3.625), p=0.001], and patients in the first group had 6 fold higher risk of mortality [OR 6.006 (CI 3.487–6.006)]. In the ROC analysis GFR showed significant predictive value for intra-hospital mortality risk in PE patients [AUC= 0.725, 95% CI (0.68–0.78), p<0.001]. The highest sensitivity (64%) and specificity (70%) had GFR “cutoff” value of 59.12/min.
Conclusion
Renal dysfunction, on admission, in patients with acute PE is strongly associated with high intrahospital mortality risk and fatal bleeding. The estimation of GFR in these patients is important not only for prediction of the outcome but also for the prevention of bleeding complications, regarding the optimal dosage of anticoagulants. Even though it seems that GFR calculation is not still the clinical routine in PE.

Abstract
In 2012, alcohol liver disease resulted in 3.3 million-5.9% of global deaths. This study introduced whey protection capacity against chronic alcohol-induced liver injury. Rats were orally administered to 12% ethanol solution in water (ad libitum, average 8.14 g of ethanol/kg body weight (b.w.)/day) alone or combined with whey ( per os, 2 g/kg b.w./day). After 6-week treatment, chronic ethanol consumption induced significant histopathological liver changes: congestion, central vein dilation, hepatic portal vein branch dilation, Kupffer cells hyperplasia, fatty liver changes, and hepatocytes focal necrosis. Ethanol significantly increased liver catalase activity and glutathione reductase protein expression without significant effects on antioxidative enzymes: glutathione peroxidase (GPx), copper-zinc-containing superoxide dismutase (CuZnSOD) and manganese-containing superoxide dismutase (MnSOD). Co-treatment with whey significantly attenuated pathohistological changes induced by ethanol ingestion and increased GSH-Px and nuclear factor kappa B (NF-κB) protein expression. Our results showed positive effects of whey on liver chronically exposed to ethanol, which seem to be associated with NF-κB-GPx signaling.

Abstract
BACKGROUND The Prenahtest study investigated the efficacy of a couple-oriented HIV counselling session (COC) in encouraging couple HIV counselling and testing, and improving intra-couple communication about sexual and reproductive health. We report here on the effect of COC on intra-couple communication about HIV. METHODS Within this 4-country trial (India, Georgia, Dominican Republic and Cameroon), 484 to 491 pregnant women per site were recruited and individually randomized to receive either the COC intervention, enhanced counselling with role playing, or standard post-test HIV counselling. Women were interviewed at recruitment, before HIV testing (T0), and 2 to 8 weeks after post-test HIV counselling (T1). Four dichotomous variables documented intra-couple communication about HIV at T1: 1) discussion about HIV, 2) discussion about condom use, 3) suggesting HIV testing and 4) suggesting couple HIV counselling to the partner. An intra-couple HIV communication index was created: low degree of communication ("yes" response to zero or one of the four variables), intermediate degree of communication ("yes" to two or three variables) or high degree of communication ("yes" to the four variables). To estimate the impact of COC on the intra-couple HIV communication index, multivariable logistic regressions were conducted. RESULTS One thousand six hundred and seven women were included in the analysis of whom 54 (3.4%) were HIV-infected (49 in Cameroon). In the four countries, the counselling group was associated with intra-couple HIV communication (P≤0.03): women allocated to the COC group were significantly more likely to report high or intermediate degrees of intra-couple communication about HIV (versus low degree of communication) than women allocated to standard counselling. CONCLUSION COC improved short-term communication about HIV within couples in different sociocultural contexts, a positive finding for a couple approach to HIV prevention.

Abstract
Intramedullary nails are commonly used to repair femoral fractures. Fractures in normal healthy bone often occur in the young during motor vehicle accidents. Although clinically beneficial, bone refracture and implant failure persist. Large variations in human femur quality and geometry have motivated recent experimental use of synthetic femurs that mimic human tissue and the development of increasingly sophisticated theoretical models. Four synthetic femurs were fitted with a T2 femoral nailing system (Stryker, Mahwah, New Jersey, USA). The femurs were not fractured in order to simulate post-operative perfect union. Six configurations were created: retrograde nail with standard locking (RS), retrograde nail with advanced locking ‘off’ (RA-off), retrograde nail with advanced locking ‘on’ (RA-on), antegrade nail with standard locking (AS), antegrade nail with advanced locking ‘off’ (AA-off), and antegrade nail with advanced locking ‘on’ (AA-on). Strain gauges were placed on the medial side of femurs. A 580 N axial load was applied, and the stiffness was measured. Strains were recorded and compared with results from a three-dimensional finite element (FE) model. Experimental axial stiffnesses for RA-off (771.3 N/mm) and RA-on (681.7 N/mm) were similar to intact human cadaveric femurs from previous literature (757 ± 264 N/mm). Conversely, experimental axial stiffnesses for AS (1168.8 N/mm), AA-off (1135.3 N/mm), AA-on (1152.1 N/mm), and RS (1294.0 N/mm) were similar to intact synthetic femurs from previous literature (1290 ± 30 N/mm). There was better agreement between experimental and FE analysis strains for RS (average percentage difference, 11.6 per cent), RA-on (average percentage difference, 11.1 per cent), AA-off (average percentage difference, 13.4 per cent), and AA-on (average percentage difference, 16.0 per cent), than for RA-off (average percentage difference, 33.5 per cent) and AS (average percentage difference, 32.6 per cent). FE analysis was more predictive of strains in the proximal and middle sections of the femur—nail construct than the distal. The results mimicked post-operative clinical stability at low static axial loads once fracture healing begins to occur.

Abstract
BACKGROUND This study evaluated the short-term and long-term effects of the angiotensin II type 1 receptor antagonist candesartan cilexetil on hemodynamics, neurohormones, and clinical symptoms in patients with congestive heart failure (CHF). METHODS In this multicenter, double-blind, parallel-group study, 218 patients with CHF (New York Heart Association class II or III) with impaired left ventricular function (ejection fraction < or =40%) and pulmonary capillary wedge pressure > or =13 mm Hg were randomly assigned to 12 weeks of treatment with placebo (n = 44) or candesartan cilexetil (2 mg [n = 45], 4 mg [n = 46], 8 mg [n = 39], or 16 mg [n = 44]) once daily after a 2-week placebo run-in period. Hemodynamic measurements were performed by right heart catheterization over a 24-hour period after single (day 1) and repeated (3-month) treatment with the study drug. RESULTS On regression analysis of the time-response curves, single and multiple doses of candesartan cilexetil produced sustained, significant, and dose-dependent reductions in pulmonary capillary wedge pressure (short-term effect P =.036, long-term effect P =.035) and mean pulmonary arterial pressure (short-term effect P =.031, long-term effect P =.042). Systemic vascular resistance showed a trend toward decreasing with dose on short-term and long-term treatments. No consistent changes were seen in cardiac index. Compensatory increases in plasma renin activity and angiotensin II levels with decreases in aldosterone and atrial natriuretic peptide were dose-dependent and significant. Candesartan cilexetil improved clinical symptoms, stabilized patient New York Heart Association status compared with placebo, and was judged to be an efficacious treatment by the investigators. More patients receiving placebo stopped the trial prematurely because of an adverse event than in any candesartan cilexetil group, and there was no excess of deaths in any treatment group. Candesartan was safe and well tolerated at all dosages. CONCLUSIONS Candesartan cilexetil demonstrated significant short-term and long-term improvements in hemodynamic, neurohormonal, and symptomatic status and was well tolerated in patients with CHF.

Abstract
Moxonidine is a new centrally active imidazoline-receptor agonist being effectively applied in the treatment of arterial hypertension due to its sympathicolytic potency. This is the first investigation regarding the effects of moxonidine on coronary and systemic hemodynamics, metabolic markers of ischemia and neurohumoral parameters in patients with essential hypertension (WHO I-II). We studied moxonidine (single dose of 0.4 mg p.o.) in 22 patients with left ventricular (LV) hypertrophy, ST segment depressions during exercise, pectanginal complaints and negative coronarograms. Assessments included arterial blood pressure, cardiac output, pulmonary artery pressure mean (PAPm), pulmonary capillary wedge pressure (PCWP) and coronary sinus flow (CSF) by intravascular Doppler technique. The moxonidine-induced parameter changes 2 hours later were as follows: a decrease in systolic/diastolic pressure by 28/10 mmHg, and in heart rate by 5 bpm, associated with a decline of PAPm by 17% and of PCWP by 26%. LV work was reduced by 26%, MVO2 by 18% and CSF by 16%. Average peak velocity in CS fell by 18% and coronary flow reserve (with adenosine) increased by 12%. CS-O2 saturation rose by 4%, accompanied by an increase in lactate extraction by 17%, a decrease in norepinephrine spillover by 30% and in arterial endotheline by 20%. In conclusion, moxonidine produces clinically relevant sympathicolysis with beneficial effects on hemodynamics, coronary circulation and neurohumoral parameters.

Abstract
Percutaneous transluminal septal myocardial ablation (PTSMA) is becoming more and more significant in the therapy of symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM). We report on the first successful PTSMA done in Yugoslavia in a 65-year old female patient with HOCM and in NYHA functional class III. The procedure was performed with infection of a relatively small amount of absolute alcohol (3 ml) in the first septal branch of LAD, and short duration of balloon inflation (3 minutes), with reduction of the left ventricular outflow tract gradient at rest from 88 mm Hg to 11 mmHg. The patient's in-hospital course was uneventful and has improved to NYHA functional class I.

Abstract
OBJECTIVE To assess immediate and late changes in left ventricular performance after mitral valve replacement (MVR) for mitral regurgitation with or without preservation of chordae tendineae. EXPERIMENTAL DESIGN a prospective, one year follow-up, study. SETTING university cardiosurgical hospital. PATIENTS Fourteen patients with symptomatic chronic mitral regurgitation were divided into Group A (n = 7), which underwent MVR with chordal preservation, and Group B (n = 7) which underwent MVR with chordal transection. METHODS Transesophageal echocardiography, obtained simultaneously with radial artery and pulmonary capillary wedge pressures over a range of loading conditions, was used to estimate left ventricular elastance (Eps), calculated as the slope of peak systolic pressure/end-systolic volume relation, and preload recruitable stroke work (PRSW). Measurements were taken intraoperatively before and after cardiopulmonary bypass, 6 hours later and 10 days later. Transthoracic echocardiography follow-up data were obtained after 3 months and one year. RESULTS Eps significantly decreased immediately after MVR (p = 0.018), with no difference among 2 groups. Eps gradually increased to preoperative levels 10 days after surgery. PRSW also significantly decreased after MVR (p = 0.01). The decrease was significantly larger in Group B (p = 0.038). During follow-up, Group A showed a significantly better ejection fraction (p = 0.008), and a smaller end-systolic volume index (p = 0.01) and left ventricular mass index (p = 0.04), than Group B. CONCLUSIONS These data support the hypothesis that chordal preservation during MVR has beneficial effects on left ventricular performance.

Abstract
Saccular aortic aneurysm arising in the ductal region, known as ductus diverticulum aneurysm, is a rare anomaly. Due to potentially malignant evolution, recognition of radiological signs associated with this anomaly during the asymptomatic phase may be important in order to plan surgical intervention in time. We report an unusual case of ductus diverticulum aneurysm combined with bicuspid aortic valve, dilatation of ascending aorta, and coronary artery disease.

Abstract
Worsening of left ventricular performance had been recognized after mitral valve replacement for mitral regurgitation. The effects of chordal preservation on ventricular performance after mitral valve replacement have been assessed. Twelve patients with mitral regurgitation were allocated to group A (undergoing mitral valve replacement with chordal preservation), or to group B (undergoing mitral valve replacement with chordal excision). Transoesophageal echocardiography was recorded simultaneously with radial artery and pulmonary capillary wedge pressures. Load was varied by withdrawal of blood from a venous line of cardiopulmonary bypass and/or nitroglycerine bolus. Ventricular performance was assessed by the slope of peak systolic pressure-end-systolic volume relation (Eps), and by the slope of the left ventricular stroke work-end-diastolic volume relationship. Eps significantly decreased immediately after mitral valve replacement (P < 0.02), with no difference among two groups. Eps gradually increased to preoperative levels 10 days after surgery. Pre-load recruitable stroke work also significantly decreased after mitral valve replacement (P = 0.01). The decrease was significantly larger in group B (P < 0.04). These data support the hypothesis that chordal preservation during mitral valve replacement has beneficial effects on left ventricular performance.

Abstract
Subaortic pseudoaneurysms of the left ventricle are rare acquired cardiac defects. They are usually associated with previous valve surgery, trauma, or aortic valve endocarditis. We describe the appearance of subaortic pseudoaneurysm 10 years after left heart catheterization in a patient with both aortic stenosis and regurgitation. The differential diagnosis of such lesions is presented.

Abstract
In this study left ventricular diastolic function at rest was evaluated in ten newly diagnosed, non-insulin-dependent diabetic patients by Doppler echocardiography, performed at the onset of disease and after 6 and 12 months of adequate glycaemic control. Glycosylated haemoglobin A1C, total cholesterol and triglyceride levels were assessed at the same time. The control group consisted of ten healthy subjects of matching age and body mass index. The following parameters of left ventricular function were evaluated: ejection fraction (EF), peak velocity of the early (E) and late atrial (A) mitral flow, A/E ratio, duration of the early (Ei) and of the atrial (Ai) filling phase, and heart rate. The diabetic patients had significantly higher total cholesterol and triglyceride levels compared with healthy subjects. These remained elevated throughout the follow-up period, in spite of improved glycaemic control. A significantly shorter duration of Ei (0.15 +/- 0.008 vs 0.18 +/- 0.004, P < 0.01) and a higher value of A (0.51 +/- 0.02 vs 0.39 +/- 0.01, P < 0.001) and A/E (1.06 +/- 0.05 vs 0.73 +/- 0.02, P < 0.001) were found in the diabetic patients before treatment. The parameters did not significantly change after 1 year of adequate glycaemic control. These results indicate a left ventricular filling abnormality which is present in newly diagnosed non-insulin-dependent diabetic patients and does not reverse with improved glycaemic control.
