Abstract
Clinical management of breakthrough cancer
pain (BTcP) is still not satisfactory despite the availability of effective pharmacological agents. This is in part linked to the lack of clarity regarding certain essential aspects of BTcP, including terminology, definition, epidemiology and assessment. Other barriers to effective management include a widespread prejudice among doctors and patients concerning the use of opioids, and inadequate assessment of pain severity, resulting in the prescription of ineffective drugs or doses. This review presents an overview of the appropriate and inappropriate actions to take in the diagnosis and treatment of BTcP, as determined by a panel of experts in the field. The ultimate aim is to provide a practical contribution to the unresolved issues in the management of BTcP. Five ‘things to do’ and five ‘things not to do’ in the diagnosis and treatment of BTcP are proposed, and evidence supporting said recommendations are described. It is the duty of all healthcare workers involved in managing cancer patients to be mindful of the possibility of BTcP occurrence and not to underestimate its severity. It is vital that all the necessary steps are carried out to establish an accurate and timely diagnosis, principally by establishing effective communication with the patient, the main information source. It is crucial that BTcP is treated with an effective pharmacological regimen and drug(s), dose and administration route prescribed are designed to suit the particular type of pain and importantly the individual needs of the patient.

Abstract
We carried out a project aimed to evaluate the possible role played by the freshwater zebra mussel (Dreissena polymorpha) in the possible decrease of some environmental pollutants recalcitrant to tradition wastewater treatments. By the help of a pilot-plant built in the largest wastewater treatment plant of Milan (Italy), we tested several waste mixtures in order to measure the chemicals' abatement made by mussels' biofiltration. This study represents the last step of the wider project and it aimed to evaluate if the decrease in the concentration of some urban pollutants measured in wastewaters was followed by a corresponding toxicity reduction. Thus, we performed 7-day exposures under laboratory conditions to test the toxicity of the raw wastewaters and those preliminary filtered by zebra mussels, through the measurement of different end-points of acute and chronic toxicity. Results showed a clear positive effect of mussels' biofiltration mainly to decrease the acute toxicity made by the two tested wastewater mixtures, while the biomarkers' suite used to evaluate the chronic toxicity showed contradictory results.

Abstract
Parents should differentially invest in sons or daughters depending on the sex-specific fitness returns from male and female offspring. In species with sexually selected heritable male characters, highly ornamented fathers should overproduce sons, which will be more sexually attractive than sons of less ornamented fathers. Because of genetic correlations between the sexes, females that express traits which are under selection in males should also overproduce sons. However, sex allocation strategies may consist in reaction norms leading to spatiotemporal variation in the association between offspring sex ratio (SR) and parental phenotype. We analysed offspring SR in barn swallows (Hirundo rustica) over 8 years in relation to two sexually dimorphic traits: tail length and melanin-based ventral plumage coloration. The proportion of sons increased with maternal plumage darkness and paternal tail length, consistently with sexual dimorphism in these traits. The size of the effect of these parental traits on SR was large compared to other studies of offspring SR in birds. Barn swallows thus manipulate offspring SR to overproduce 'sexy sons' and potentially to mitigate the costs of intralocus sexually antagonistic selection. Interannual variation in the relationships between offspring SR and parental traits was observed which may suggest phenotypic plasticity in sex allocation and provides a proximate explanation for inconsistent results of studies of sex allocation in relation to sexual ornamentation in birds.

Abstract
One of the fundamentals in the ecotoxicological studies is the need of data comparison, which can be easily reached with the help of a standardized biological model. In this context, any biological model has been still proposed for the biomonitoring and risk evaluation of freshwaters until now. The aim of this review is to illustrate the ecotoxicological studies carried out with the zebra mussel Dreissena polymorpha in order to suggest this bivalve species as possible reference organism for inland waters. In detail,we showed its application in biomonitoring, as well as for the evaluation of adverse effects induced by several pollutants, using both in vitro and in vivo experiments. We discussed the advantages by the use of D. polymorpha for ecotoxicological studies, but also the possible limitations due to its invasive nature.

Abstract
The increase in global consumption of illicit drugs has produced not only social and medical problems but also a potential new environmental danger. Indeed, it has been established that drugs consumed by humans end up in surface waters, after being carried through the sewage system. Although many studies to measure concentrations of several drugs of abuse in freshwater worldwide have been conducted, no data have been available to evaluate their potentially harmful effects on non-target organisms until now. The present study represents the first attempt to investigate the cyto-genotoxic effects of cocaine, one of the primary drugs consumed in Western Countries, in the biological model Dreissena polymorpha by the use of a biomarker battery. We performed the following tests on Zebra mussel hemocytes: the single cell gel electrophoresis (SCGE) assay, the apoptosis frequency evaluation and the micronucleus assay (MN test) for the evaluation of genotoxicity and the lysosomal membranes stability test (neutral red retention assay; NRRA) to identify the cocaine cytotoxicity. We exposed the molluscs for 96 h to three different nominal concentrations in water (40 ng L(-1); 220 ng L(-1); and 10 μg L(-1)). Cocaine caused significant (p<0.05) primary DNA damage in this short-term experiment, but it also caused a clear increase in micronucleated cells and a marked rise in apoptosis, which was evident in samples from even the lowest environmental cocaine concentration. Because cocaine decreased the stability of lysosomal membranes, we also highlighted its cytotoxicity and the possible implications of oxidative stress for the observed genotoxic effects.

Abstract
This paper presents a full-scale experience of sludge minimization by means of short contact time ozonation in a wastewater treatment plant (WWTP) mainly fed on textile wastewater. The WWTP performance over a 3-year operational data series was analysed and compared with a two-year operation with sludge ozonation. Lab-scale respirometric tests were also performed to characterize biomass activity upstream and downstream of the ozone contact reactor. Results suggest that sludge ozonation: (1) is capable of decreasing excess sludge production by 17%; (2) partially decreases both N removal, by lowering the denitrification capacity, and P removal, by reducing biomass synthesis; (3) increases the decay rate from the typical value of 0.62 d(-1) to 1.3 d(-1); (4) decreases the heterotrophic growth yield from the typical value of 0.67 to 0.58 gCOD/gCOD.

Abstract
A battery of eight biomarkers was applied in the freshwater mussel Dreissena polymorpha to evaluate potential sub-lethal effects of the antimicrobial trimethoprim (TMP, 5-[3,4,5-trimethoxybenzyl]pyrimidine-2,4-diamine). Mussels were exposed for 96 h to increasing concentrations (1, 3, 10 nM) of TMP in in vivo experiments. We determined the single cell gel electrophoresis (SCGE) assay, the micronucleus test (MN test), the apoptotic frequency (Halo assay) and the lysosomal membrane stability (Neutral Red Retention Assay) in mussel hemocytes. Moreover, to reveal whether the oxidative status was altered, measurements of the activity of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and the phase II detoxifying enzyme glutathione S-transferase (GST) were performed using the cytosolic fraction extracted from a pool of entire mussels. The biomarker battery pointed out only a moderate cyto- and genotoxicity on Zebra mussel hemocytes since only a slight increase in DNA damage was registered by apoptosis induction and MN frequency, while significant differences of lysosomal membrane stability from baseline levels were measured at 3 and 10 nM at the end of exposures only. Finally, TMP seems to have a very low induction capability or even an inhibitory effect on the activities of antioxidant enzymes, but a clear significant induction on GST.

Abstract
Pharmaceuticals and personal care products (PPCPs) have been detected in several aquatic ecosystems for a number of years, but the potential for biological effects in exposed non-target organisms is only now being reported. In this study the potential cellular damage due to two of the main PPCPs found in aquatic environments was investigated by in vitro exposures. Hemolymph samples of the freshwater bivalve Dreissena polymorpha were collected and treated with increasing concentrations of the antibacterial agent Triclosan (TCS) and the antibiotic Trimethoprim (TMP). Doses selected for TCS were 0.1, 0.15, 0.2, and 0.3 microM, while 0.2, 1, and 5 microM for TMP exposures, respectively. We evaluated the potential genotoxicity on hemocytes by the SCGE (single cell gel electrophoresis) assay and apoptosis frequency evaluation, while the cytotoxicity was measured by the lysosomal membranes stability test (NRRA, neutral red retention assay). TCS genotoxicity increased in a dose-dependent manner and this pharmaceutical significantly affects hemocyte functionality due to severe DNA injuries at very low doses. In contrast, TMP seems to be less dangerous than TCS for D. polymorpha because the cytotoxic and the moderate genotoxic effects noticed were obtained only at very high concentration levels.

Abstract
In this work, we investigated the possible genotoxic and cytotoxic effects of the antibacterial agent Triclosan in hemocytes of the freshwater bivalve Zebra mussel (Dreissena polymorpha). For this study, we used several biomarkers for in vivo experiments (96h of exposure) carried out at three possible environmental Triclosan concentrations (1, 2, 3nM). We used the single cell gel electrophoresis (SCGE) assay, the micronucleus test (MN test) and the measure of the apoptotic frequency (Halo assay) to measure the genotoxic potential of Triclosan, and the neutral red retention assay (NRRA) as a measure of lysosomal membrane stability to identify general cellular stress. We observed significant increases in all of the genotoxic biomarkers examined as early as 24h after initial exposure, as well as a clear destabilization of lysosomal membranes (after 48h), indicating that this chemical is potentially dangerous for the entire aquatic biocoenosis. A comparison of these in vivo data with existing data from in vitro experiments allowed us to suggest possible mechanisms of action for Triclosan in this bivalve. Although further studies are needed to confirm the possible modes of action, our study is the first to report on the effects of this widespread antibiotic on freshwater invertebrates.

Abstract
This paper presents the first comprehensive report of the organochlorine pesticide residues (OCs) such as hexachlorocyclohexane isomers (HCHs), dichlorodiphenyltrichloroethane and its six metabolites (DDTs), and hexachlorobenzene (HCB) in core sediments (<63-microm particle size) from the Indian Sunderban wetland. The pooled mean values of the mass fraction of SigmaHCHs, HCB, and SigmaDDTs in the sediments were 0.05-12, 0.05-1.4, and 0.05-11.5 ng g(-1) dry weight, respectively. The vertical distribution of pesticides reveals an erratic pattern. The concentration of four isomers of HCHs reveals a heterogenic distribution where gamma-HCH (lindane) and beta-HCH shared the dominant part. The mass fraction of HCB did not show any sharp spatial variation. The prevailing sequence of DDT metabolites indicates an active degradation of the parent compound in the sediments and/or inputs of already degraded pp'DDT to the region. Peak concentrations of HCH isomers and DDT metabolites have the potential to induce ecotoxicological impact as per the sediment quality guidelines.

Abstract
BACKGROUND The term "myocytolysis" was first used to define the repair process of contraction band necrosis associated with an acute myocardial infarction. On the other hand, in the latter condition a "myofibrillolysis," presenting edematous myocardial cells not involved by infarct necrosis, and without evidence of repair process was reported. The objective of this study is to establish the frequency, extent and meaning of this myocardial lesion. MATERIALS AND METHODS In 12 groups of patients for a total of 432 cases with and without coronary heart disease, "colliquative myocytolysis"--i.e., progressive vacuolization by loss of myofibrils until their total or subtotal disappearance associated with intramyocellular edema in absence of any cellular reaction--was graded in 16 histological slides of the different cardiac regions in each pathological case. RESULTS Colliquative myocytolysis (CM) was present in more than 90% with a maximal extent in cases of irreversible congestive heart failure followed by transplanted heart cases (67%) with a survival greater than 1 week. In all other groups, the lesion was absent or minimal. CONCLUSIONS No correlation was found between CM and contraction band necrosis, gender, age, heart weight, myocardial fibrosis, coronary artery stenosis, clinical data. Colliquative myocytolysis is a specific histological marker of congestive heart failure, without relation to coronary blood flow, heart weight and myocardial fibrosis. Vacuolization of myocardial cells may be due to other causes (e.g., storage disease, etc.) or may be an artifact. There is no support for the belief that coronary ischemia or myocardial hypoxia is its causes.

Abstract
OBJECTIVES To assess the value of the European system for cardiac operative risk evaluation (EuroSCORE), a validated model for prediction of in-hospital mortality after cardiac surgery, in predicting long term event-free survival. DESIGN AND SETTING Single institution observational cohort study. PATIENTS Adult patients (n = 1230) who underwent cardiac surgery between January 2000 and August 2002. RESULTS Mean age was 65 (11) years and 32% were women. Type of surgery was isolated coronary artery bypass grafting in 62%, valve surgery in 23%, surgery on the thoracic aorta in 4%, and combined or other procedures in 11%. Mean EuroSCORE was 4.53 (3.16) (range 0-21); 366 were in the low (0-2), 442 in the medium (3-5), 288 in the high (6-8), and 134 in the very high risk group (> or = 9). Information on deaths or events leading to hospital admission after the index discharge was obtained from the Regional Health Database. Out of hospital deaths were identified through the National Death Index. In-hospital 30 day mortality was 2.8% (n = 34). During 2024 person-years of follow up, 44 of 1196 patients discharged alive (3.7%) died. By Cox multivariate analysis, EuroSCORE was the single best independent predictor of long term all cause mortality (hazard ratio (HR) 1.55, 95% confidence interval (CI) 1.03 to 2.34, p < 0.0001). In the time to first event analysis, 227 either died without previous events (n = 20, 9%) or were admitted to hospital for an event (n = 207, 91%). EuroSCORE (HR 1.60, 95% CI 1.36 to 1.89, p < 0.0001), the presence of > or = 2 co-morbidities versus one (HR 1.49, 95% CI 1.09 to 2.02, p < 0.0001), and > 96 hours' stay in the intensive care unit after surgery (HR 2.04, 95% CI 1.42 to 2.95, p = 0.0001) were independently associated with the combined end point of death or hospital admission after the index discharge. CONCLUSIONS EuroSCORE and a prolonged intensive care stay after surgery are associated with long term event-free survival and can be used to tailor long term postoperative follow up and plan resource allocation for the cardiac surgical patient.

Abstract
BACKGROUND Myocardial disarray is a structural abnormality found in specific zones of the normal heart. In some conditions, such as hypertrophic cardiomyopathy (HCM), its occurrence represents a pathological process leading to myocardial asynergy. The incidence of "pathological" myocardial disarray in humans is still not known. It has been suggested that a link exists between adrenergic overactivity and myocardial disarray. The aim of the present study is to compare heart findings in conditions with and without chronic sympathetic overtone for evidence of possible linkage in humans. MATERIALS AND METHODS A total of 340 hearts were studied. They were divided into seven groups: sudden/unexpected coronary death; sudden/unexpected death in silent Chagas' disease; brain haemorrhage following berry aneurysm rupture; transplanted hearts; congestive heart failure, AIDS and cocaine abuse. Findings in these hearts were compared with anatomic changes in 92 control hearts, where the decedent had died from head trauma, electrocution, or carbon monoxide intoxication. The frequency and presence of myocardial disarray were recorded and correlated to heart weight, extent of myocardial fibrosis, and contraction band necrosis (CBN). RESULTS Hearts from patients with conditions that increased sympathetic tone showed an association of myocardial disarray and contraction band necrosis without any relationship to heart weight. CONCLUSIONS Myocardial disarray was observed in cardiac areas where it is not found normally. It was associated with adrenergic myocardial stress morphologically expressed by a higher number of foci (p<0.01) and myocells (p<0.001) with CBN versus findings in normal subjects. The condition deserves further study as a possible myocardial asynergic and arrhythmogenic factor especially in sudden/unexpected death.

Abstract
This study was designed to assess the parameters of myocardial oxidative stress and related cardiac morphological changes following intraperitoneal cocaine exposure in rats. The cardiac levels of reduced glutathione(GSH), oxidised glutathione(GSSG), ascorbic acid (AA), and the production of malondialdehyde (MDA) were measured, as well as the variations of activity in the enzyme systems involved in cell antioxidant defence, glutathione peroxidase (GSH-Px), glutathione reductase (GR) and superoxide dismutase (SOD). After chronic cocaine administration for 30 days GSH was significantly depleted in the heart from 30 min (P < 0.001) to 24 h (P < 0.001) after exposure, and GSSG was increased for a similar time (P < 0.05 at 30 min and P < 0.01 at 24 h). SOD increased during the first hour (P < 0.001), GR and GSH-Px both increased from 30 min to 24 h, and these increases were statistically significant (P < 0.01 and P < 0.001 at 30 min and P < 0.01 and P < 0.001 at 24 h, respectively). The AA levels increased after 1 h (P < 0.01), remaining significantly so for 24 h (P < 0.001) and MDA increased from 30 min to 24 h, all values being highly significant (P < 0.001). The body weight was significantly (P < 0.001) reduced in both cocaine groups (40 mg/kg x 30 days and 40 mg/kg x 10 days + 60 mg/kg x 20 days). The heart weight (P < 0.01) and its percentage of the body weight (P < 0.001) were significantly higher in these two groups than in the controls. Similarly, in the noradrenaline 4 mg/ kg x 30 days group, the body weight was significantly (P < 0.001) reduced and the heart weight (P < 0.01) and its percentage of body weight (P < 0.001) were significantly higher than in the controls. In comparing the cocaine and noradrenaline experiments, the frequency and extent of cardiac lesions obtained with 40 mg/kg x 10 days + 60 mg/kg x 20 days of cocaine were similar to those with 8 mg/kg of noradrenaline at 24 h. In this experimental model, cocaine administration compromised the antioxidant defence system of the heart associated with a significant increase of heart weight and the percentage of body weight.

Abstract
Pathological contraction bands affecting myocardial cells are observed in many different human conditions and in different experimental models. Their morphology was defined long ago but we need to understand the pathogenesis and functional meaning. A distinction between different histological forms of contraction bands and their quantification in a large spectrum of human diseases (262 cases) and a normal population sample where death was due to various types of accidental death (170 cases) produced the following conclusions: 1) The term "contraction band necrosis", as used presently, is ambiguous and should be reserved for a specific morpho-functional entity induced experimentally by intravenous catecholamine infusion and seen in equivalent human cases with pheochromocytoma. 2) In human pathology it may represent a sign of adrenergic stress linked with malignant arrhythmia/ventricular fibrillation. 3) Beyond a histological threshold of 37+/-7 foci and 322+/-99 myocells/100 mm2, the lesion may indicate sympathetic overdrive in the natural history of a disease and associated arrhythmogenic supersensitivity. 4) The detection of few pathological contraction bands in normal subjects in some types of accidental death correlates with the survival time, suggesting an agonal adrenergic stimulation to promote the cardiac pump.

Abstract
AIMS To evaluate the accuracy of echocardiography in conjunction with quantitative high-dose dipyridamole technetium-99m sestamibi tomography (SPECT) in detecting coronary allograft vasculopathy. METHODS AND RESULTS Seventy-eight consecutive heart transplant recipients underwent echocardiography while at rest and high-dose dipyridamole SPECT within 48 h of a yearly angiogram. Resting wall motion abnormalities were considered significant if present in two or more segments. SPECT was considered abnormal in the presence of reversible/fixed defects. The coronary angiogram was normal in 53, showed non-significant coronary allograft vasculopathy in 13 and significant (> or = 50% stenosis) coronary allograft vasculopathy in 12 cases. Resting wall motion abnormalities were observed in nine cases and perfusion defects in 20. Echocardiography and SPECT were concordant in 59 cases (five positive and 54 negative); in these, accuracy was 100% for significant coronary allograft vasculopathy and 83% for any coronary allograft vasculopathy. Over 6.5+/-2 years, 17 patients suffered coronary allograft vasculopathy-related events, including death in six and retransplantation in three. Resting wall motion abnormalities, SPECT perfusion defects and angiographic coronary allograft vasculopathy were significant predictors of cardiac events. CONCLUSION Normal resting wall motion at echocardiography coupled to normal stress myocardial perfusion, rules out the presence of significant coronary allograft vasculopathy in many heart transplant recipients. Conversely, resting wall motion abnormalities and perfusion defects strongly predict cardiac events. Therefore, a strategy which reserves angiography for patients with resting wall motion abnormalities and/or perfusion defects may be safe and cost-effective.

Abstract
The aim of this study was to define the status of the myocardium in selected human cases of acute, fatal carbon monoxide intoxication and the myocardial changes in rats exposed to carbon monoxide in relation to the type of cardiac arrest and the effects of reoxygenation following pre-fatal CO intoxication. The human study consisted of 26 cases (17 accidental and 9 suicide) of acute, fatal CO intoxication, without evidence of obstructive coronary atherosclerosis or history of ischemic heart disease which were compared with 45 cases of fatal head trauma in subjects who died instantaneously (26 cases) or within 1-12 h (19 cases). Inhalation of a lethal dose of CO in rats was compared with sub-lethal doses plus reoxygenation with and without pre-treatment by a betablocker. In all human and experimental histological sections, changes were normalised per mm2 area. In the human cases the myocardium did not show any ischemic types of changes or other lesions. Only in "three accidental" cases a few, small foci of coagulative myocytolysis were detected. In the case of spontaneous death in 31 rats following CO intoxication, no pathological myocardial changes were seen. Of the 15 "reoxygenated" rats, 2 of the 7 spontaneous deaths presented coagulative myocytolysis with 15 +/- 6 foci and 381 +/- 255 necrotic myocells. All the eight rats sacrificed at 3 h had coagulative myocytolysis with 5 +/- 4 foci and 60 +/- 47 myocells. Of the 24 reoxygenated rats pre-treated with a betablocker, 5 died spontaneously after a short survival and 2 of these showed 11 +/- 9 foci and 21 +/- 20 myocells. The 19 rats sacrificed after 3 h all presented coagulative myocytolysis with figures of 75 +/- 43 and 356 +/- 301 with 0.5 mg/kg of propranolol hydrochloride and 55 +/- 45 and 253 +/- 216 with 2 mg/kg, respectively.

Abstract
BACKGROUND Beta-blockers improve survival and ventricular function in patients with heart failure. We evaluated the long-term persistence of metoprolol-induced improvement and its impact on prognosis in idiopathic dilated cardiomyopathy. METHODS Two hundred and four of 586 patients enrolled in a registry on the natural history of idiopathic dilated cardiomyopathy survived 4 years without transplantation; 98 of them were on standard heart failure treatment, whereas 106 took metoprolol in addition. We analyzed the effects of treatment using beta-blockers in terms of changes in left ventricular ejection fraction (LVEF), NYHA functional class and left ventricular end-diastolic diameter index (LVEDDI) after 1, 2 and 4 follow-up years in order to elaborate an improvement score that was related to the subsequent outcome over 60 months after the 4-year follow-up visit. RESULTS Greater LVEF increases and NYHA functional class and LVEDDI decreases were observed in patients submitted to metoprolol vs standard treatment at all stages of follow-up. Changes (delta vs baseline) for LVEF (p = 0.02), NYHA functional class (p = 0.0001) and LVEDDI (p = 0.004) were maximal during the first year (10 +/- 11 vs 6 +/- 12 units, -0.72 +/- 0.77 vs -0.23 +/- 0.81, -3.5 +/- 5 vs -1.6 +/- 3.5 mm), persisted at 2 (12 +/- 12 vs 8 +/- 12 units, -0.80 +/- 0.70 vs -0.37 +/- 0.87, -4.2 +/- 5 vs -2.3 +/- 4 mm) but showed a trend to decline at 4 years (11 +/- 12 vs 8 +/- 13 units, -0.54 +/- 0.90 vs -0.24 +/- 0.91, -4.3 +/- 5 vs -2.3 +/- 5 mm) of follow-up. Improvement at 4 years was associated with a better transplant-free survival (81 vs 52%, p = 0.0005, odds ratio 0.36, 95% confidence interval 0.18 to 0.74). CONCLUSIONS In idiopathic dilated cardiomyopathy, the more significant improvement in symptoms and left ventricular function and size, that is observed following treatment using metoprolol, translates into a better outcome. These benefits peak within the first 2 years of start of treatment but may begin to fade thereafter.

Abstract
Excessive ethanol intake is reported in 3% to 40% of patients with idiopathic dilated cardiomyopathy (IDC). In the prevasodilator era, the prognosis was reportedly better in alcoholic than in IDC patients, an advantage limited to abstinent patients. No large series of patients systematically treated with angiotensin-converting enzyme inhibitors has since been described. We analyzed long-term outcome according to alcohol abuse in male patients with IDC. Among 338 men who had been prospectively enrolled in a multicenter registry, 79 (23%) were defined as alcohol abusers and further classified at follow-up as having stopped (AAS) or continued (AAC) abuse. AAC subjects at enrollment reported a higher daily alcohol intake than AAS subjects (178 +/- 113 vs 127 +/- 54 g/day, p = 0.012). During a mean of 59 +/- 35 months, 102 patients died and 45 underwent transplantation. Seven-year transplant-free survival was significantly lower in alcohol abusers (41%) than in patients with IDC (53%, p = 0.026), and significantly lower in AAC subjects (27%) than in either patients with IDC or AAS (45%) (p = 0. 018). Although IDC patients had beneficial changes in left ventricular function at follow-up, only AAS patients had significant improvement in ejection fraction. In this large series of patients treated with angiotensin-converting enzyme inhibitors and prospectively followed up, excessive alcohol intake was found in about one fourth of cases and persistent alcohol abuse correlated with a worse prognosis and function at follow-up.

Abstract
BACKGROUND The temporal response of the left ventricle due to the relief of volume loading after mitral valve repair, and the prognostic value of early changes in left ventricular size and function, are not fully documented. The purpose of this study was to analyze the evolution of left ventricular performance after surgery, and to evaluate how early postoperative echocardiographic parameters compare with late ventricular function. METHODS We studied 58 patients with chronic degenerative mitral regurgitation using echocardiography, before, and 9 +/- 3 days and 38 +/- 6 months after mitral valve repair. RESULTS Between the preoperative and early postoperative study, left ventricular end-diastolic and left atrial size, and ejection fraction decreased, whereas left ventricular end-systolic dimension did not change. Between the early and late postoperative study left ventricular end-systolic size decreased significantly, there was a further decrease in left ventricular end-diastolic dimension and a significant increase in ejection fraction; left atrial size did not change. Multivariate analysis showed that preoperative and early postoperative ejection fraction, and the early postoperative reduction in diastolic dimension were the best predictors of late left ventricular function. CONCLUSIONS In patients with chronic degenerative mitral regurgitation, the greatest reduction in end-diastolic dimension occurs within 2 weeks of the reversal of volume overload; a significant reduction in end-systolic dimension with an increase in ejection fraction occurs later. In our experience, early postoperative echocardiographic measurements of left ventricular size and function can provide important prognostic information.

Abstract
OBJECTIVE To evaluate the additive effect of metoprolol treatment on long-term incidence of fatal and non-fatal cardiac events in idiopathic dilated cardiomyopathy. DESIGN 586 patients with idiopathic dilated cardiomyopathy were prospectively enrolled in a multicentre registry and followed up for a mean (SD) of 52 (32) months. Metoprolol, carefully titrated to the maximum tolerated dose, was added to conventional heart failure treatment in 175 patients. RESULTS Survival and transplant-free survival at seven years were significantly higher in the 175 metoprolol treated patients than in the remaining 411 on standard treatment (81% v 60%, p < 0.001, and 69% v 49%, p < 0.001, respectively). By multivariate analysis, metoprolol independently predicted survival and transplant-free survival (relative risk reduction values for all cause mortality and combined mortality or transplantation 51% (95% confidence interval 21% to 69%), p = 0.002, and 34% (5% to 53%), p = 0.01, respectively). New York Heart Association class, left ventricular end diastolic diameter, and pulmonary wedge pressure were also predictive. Seven year survival (80% v 62%, p = 0.004) and transplant-free survival (68% v 51%, p = 0.005) were significantly higher in 127 metoprolol treated cases than in 127 controls selected from the entire control cohort and appropriately matched. Metoprolol was associated with a 30% reduction in all cause mortality (7% to 48%, p = 0.015) and a 26% reduction in mortality or transplantation (7% to 41%, p = 0.009). CONCLUSIONS The addition of metoprolol to standard heart failure treatment, including angiotensin converting enzyme inhibitors, was effective in the long-term, reducing both all cause mortality and transplantation in patients with idiopathic dilated cardiomyopathy.

Abstract
BACKGROUND The structural correlates of 201Tl uptake in patients with advanced postischemic pump dysfunction are unclear. There are no good experimental models adequately reflecting the mixture of normal, dysfunctional but viable, and necrotic regions characteristic of chronic ischemic heart disease in human beings. METHODS AND RESULTS Four heart transplant candidates with idiopathic dilated cardiomyopathy and seven with ischemic heart disease underwent rest-injection 4-hour redistribution 201Tl single-photon emission computed tomography before surgery. Delayed tracer uptake was categorized into severely reduced (<50%), mildly or moderately reduced (50% to 74%), and normal (> or =75%) and related to echocardiographic wall motion and histologic findings in the hearts excised at transplantation. In idiopathic dilated cardiomyopathy, despite severe wall motion impairment, minimal or mild myocardial damage and homogeneously high 201Tl uptake were found. In ischemic heart disease, wall motion did not discriminate extensive from mild structural damage. 201Tl activity was inversely related to myocardial fibrosis (r = -0.50, p = 0.0001). Severe defects in 201Tl uptake (<50%) predicted extensive (>30%) fibrosis with 83% sensitivity and 63% specificity. Segmental akinesis and apical location resulted in loss of sensitivity (74% and 58%, respectively). No histologic or wall motion abnormality accounted for poor specificity. In the individual patient, more than nine segments determined viable by imaging criteria predicted left ventricular fibrosis of less than 15% with 86% accuracy. CONCLUSIONS This histopathologic-clinical correlative study supports current evidence of good sensitivity but limited specificity of 201Tl rest-redistribution tomographic imaging in the evaluation of viable myocardium. In the individual patient, more than nine viable segments reliably predicted a limited extension of fibrosis.

Abstract
To determine the morphological bases of thallium-201 myocardial distribution in chronic cardiac dysfunction and their relation to myocardial blood flow, myocardial slices from ten excised hearts of five chronic ischaemic heart disease patients and five idiopathic dilated cardiomyopathy patients, were imaged on a gamma camera to quantitate the uptake of thallium-201, injected 4 h before surgery, and myocardial blood flow from distribution of technetium-99m-labelled human albumin microspheres injected during surgery. Tracer distribution was correlated with histologically assessed myocardial fibrosis and myocytolysis. Thallium-201 uptake was inversely related to fibrosis (r = -0.73, in ischaemic heart disease, r = -0.65 in idiopathic dilated cardiomyopathy). In ischaemic heart disease, myocardial blood flow was related neither to thallium-201 uptake (r = 0.41) nor to the extent of fibrosis (r = -0.48). In this group, segments with normal or mildly reduced thallium-201 uptake showed significantly lower fibrosis than those with moderate or severe uptake defects (5 +/- 7% and 7 +/- 11% vs 33 +/- 14% and 42 +/- 12%, respectively, P < 0.0001. In a clinical model of chronic ischaemic dysfunction, despite severely depressed myocardial blood flow, extensive areas of myocardium devoid of significant structural impairment are present. Thallium-201 uptake effectively discriminates regions with preserved viability from those with relevant myocardial damage.

Abstract
BACKGROUND Knowledge of time course and risk factors for morbidity and mortality may allow better cardiac graft allocation, surveillance timing, and planning of immunosuppressive strategies. METHODS Six-month morbidity and mortality were retrospectively analyzed in a multiinstitutional series of 645 heart transplant recipients. RESULTS During a 3432 patient-months follow-up, 87 patients died of infection (n = 11), rejection (n = 11), multiorgan failure (n = 9) and other transplant-related causes (n = 56); six-month survival rate was 86%. Three hundred thirty-seven recipients had 967 treated rejection episodes (2.87 episodes/patient with rejection, lethality 3.2%); 223 major infectious episodes occurred in 162 patients (1.38 episodes/infected patient, lethality 7%). Six-month rejection and infection-free survival rates were 44% and 73%. Total mortality and cause-specific morbidity sharply declined after the first month; 160 patients (25%) had no events during follow-up. At multivariable analysis, significant risk factors for mortality were postoperative acute kidney failure, prolonged cardiopulmonary bypass time, and previous cardiac surgery. Rejection was associated with steroid-free and globulin-free immunosuppression and infection was associated with steroid immunosuppression, cytolytic treatment, venous lines placement greater than 7 days, and mechanical ventilation time. No single or combination of variables was able to discriminate patients with an event-free course. CONCLUSIONS Morbidity and mortality have the highest incidence during the early posttransplantation phase. Preoperative variables are of limited value with respect to immunosuppressive treatment in predicting outcome. Infection is far less frequent than rejection but, in view of the higher lethality rate, deserves a vigorous effort for prevention, which is best addressed by appropriate modulation of immunosuppressive strategies.
