ABSTRACT
BACKGROUND: In the last decades, the issues related to health risk communication to stakeholders and citizens involving health care practitioners and local political authorities have been increasingly debated. The study evaluated an alternative strategy to communicate cancer risk to local communities, involving an expert panel of public health operators in comparing two different graphic tools, Funnel Plot and Choropleth map. STUDY DESIGN: A Delphi method process was implemented to achieve a unified consensus on an expert panel of public health operators with regard to weaknesses and strengths of the Funnel Plot and the Choropleth map as tools for cancer risk communication to local communities and other stakeholders. METHODS: Participants were asked to score the efficacy of the two tools using a scale. Six properties were explored through two consecutive consensus rounds. Scales were used to calculate frequencies and the content validity ratio for each domain within the consensus rounds. RESULTS: After the two consecutive rounds, participants expressed their preference in favour of the Choropleth map for its ability to define the spatial location of the risk and to locate any potential cluster, while reaching a consensus with regard to the Funnel Plot properties to identify hot spots, displaying the scope of the phenomenon under investigation, and to show the precision of estimates and communicating the significance of estimates. CONCLUSIONS: The Delphi process allowed us to conclude that Funnel Plot could be used as a complement to the current and commonly used graphical and visual formats to effectively communicate cancer epidemiological data to communities and local authorities, representing a useful tool for empowering the general population.

We thought that delirium might be less frequent after transcatheter aortic valve implantation via the femoral artery compared with via the cardiac apex. We reviewed 210 patients who underwent transcatheter aortic valve implantation between January 2009 and October 2014. The proportion (95% CI) of patients who suffered delirium in the 3 days after valve implantation were: 10 (3-16%) in 105 patients who had transfemoral implantation; and 35 (25-45%) in 105 patients who had transapical implantation, p = 0.0001. The variables that independently associated with postoperative delirium were age, male sex and the transapical approach. The median (IQR [range]) hospital stay was 7 (5-13 [2-41]) days and 10 (7-15 [2-64]) days, respectively, p = 0.004. Future trials should focus on different peri-operative management strategies to reduce delirium rates after transcatheter aortic valve implantation, particularly in older men having implantations via the cardiac apex.

BACKGROUND: Persons living after a cancer diagnosis represent 4% of the whole population in high-income countries. The aim of the study was to provide estimates of indicators of long-term survival and cure for 26 cancer types, presently lacking. PATIENTS AND METHODS: Data on 818 902 Italian cancer patients diagnosed at age 15-74 years in 1985-2005 were included. Proportions of patients with the same death rates of the general population (cure fractions) and those of prevalent patients who were not at risk of dying as a result of cancer (cure prevalence) were calculated, using validated mixture cure models, by cancer type, sex, and age group. We also estimated complete prevalence, conditional relative survival (CRS), time to reach 5- and 10-year CRS >95%, and proportion of patients living longer than those thresholds. RESULTS: The cure fractions ranged from >90% for patients aged <45 years with thyroid and testis cancers to <10% for liver and pancreatic cancers of all ages. Five- or 10-year CRS >95% were both reached in <10 years by patients with cancers of the stomach, colon-rectum, pancreas, corpus and cervix uteri, brain, and Hodgkin lymphoma. For breast cancer patients, 5- and 10-year CRSs reached >95% after 19 and 25 years, respectively, and in 15 and 18 years for prostate cancer patients. Five-year CRS remained <95% for >25 years after cancer diagnosis in patients with liver and larynx cancers, non-Hodgkin lymphoma, myeloma, and leukaemia. Overall, the cure prevalence was 67% for men and 77% for women. Therefore, 21% of male and 31% of female patients had already reached 5-year CRS >95%, whereas 18% and 25% had reached 10-year CRS >95%. CONCLUSIONS: A quarter of Italian cancer patients can be considered cured. This observation has a high potential impact on health planning, clinical practice, and patients' perspective.

Intimal (spindle cell) sarcomas of the left atrium are extremely rare primary cardiac tumours with three cases reported (Li et al. (2013), Cho et al. (2006), and Modi et al. (2009)). We present a 69-year-old man who first came to medical attention after experiencing abdominal discomfort. He had a 30 lb weight loss apparently due to dieting. He denied any other constitutional symptoms. His symptoms persisted despite a course of antibiotics for presumed diverticulitis. Laboratory values were within normal limits, though the haemoglobin was 131 g/L (normal: 140-180). Subsequent abdominal computed tomography (CT) scan revealed an abdominal wall mass and intracardiac lesion; the cardiac mass was further characterized by transesophageal echo (TEE), magnetic resonance imaging (MRI), and dedicated cardiac CT. TEE revealed a mass attached to the posterolateral wall of the left atrium above the mitral annulus, and the cardiac CT and MRI confirmed the TEE findings. The patient underwent extensive surgical resection and repair of the left side of the heart. Postoperatively, he developed acute renal failure requiring dialysis and reintubation for volume overload. He became acutely hypotensive, developed multiorgan failure, and succumbed to his illness. Histopathologic examination of the left atrial mass showed an intimal sarcoma.
ABSTRACT
Atrial masses postcardiac transplant are not well reported and their diagnosis and treatment can be challenging. In the asymptomatic patient, differentiating thrombus from cardiac tumor can sometimes be difficult and the use of multiple imaging modalities is recommended. Accurate diagnosis is imperative to inform a treatment plan that balances the benefits and risks of a medical versus surgical approach. We present three cases of atrial masses postcardiac transplant to illustrate this clinical dilemma.

INTRODUCTION: The aim of this paper is to improve the feasibility perception of policymakers, health care workers and target population about the cost-effectiveness of the implementation of colorectal screening as Public Health strategy. METHODS: Retrospective study by application of a three-step model designed for a local setting in Sicily (Palermo and its Province) in order to distribute Fecal Occult Blood Tests (FOBTs), offer colonoscopy and surgery, by district allocation of pharmacies, public digestive endoscopic centres and oncologic and general surgery units. Mean adherence to consolidated colorectal screening programs in Italy was applied in order to evaluate the feasibility of an operative model in our area. RESULTS: Applying the model to the target population (269,368 individuals of both sexes), it can be expected a mean percentage of 79% delivered invitation and a mean participation rate of 46.3% accounting for a total of 213,070 invited individuals and 98,651 participating in the first round of the program. Furthermore, considering the national mean of 6% positive FOBT, 82% of colonscopy adhesion and 7% CRC detection rate, it can be scheduled a burden for health care structures involved in the program accounting for 49,325 FOBTs, 2,338 colonscopies and 141 surgeries for each year. DISCUSSION: This work demonstrates the feasibility of a colorectal screening project in our area, showing a sustainable impact for local health care involved structures. Furthermore, this program may be spread as an applicative model to other areas, adapting the project to the needs of the local setting in which the colorectal screening will be organized.

Papillary fibroelastomas (PFEs) are benign cardiac tumours that typically arise on diseased aortic or mitral valves. Usually solitary, PFEs are characterised by numerous frond-like branches attached to the valve surface by a single stalk, elastic tissue present within the central core, and the appearance of a sea anemone when immersed in water. PFEs have a predilection for men with a mean age of 56 years. A very rare case of a 25-year-old man with multiple lesions on the aortic and mitral valves and a large confluent "carpet-like" lesion in the left ventricular cavity is presented. Admitted with a significant left middle cerebral artery stroke and hemiplegia, investigations showed a left ventricular outflow tract lesion, with surgical excision displaying a multifocal "carpet-like" PFE. Histopathological examination showed various lesions presenting with a short stem, several fronds arising from each stem like a "tree trunk", and elastic tissue within the central core. This case is presented, along with a review of 833 reported cases of PFEs published after the year 2001. It is believed that this is the first reported instance of surgically resected and morphologically confirmed multiple PFEs seen and removed at one operation.

BACKGROUND: Implantation of a left ventricular assist device (LVAD) is an acceptable therapy for patients with advanced heart failure. LVADs may be used as a bridge to recovery, a bridge to transplantation or as destination therapy. Although the morbidity rate of individuals on device support remains high, experience suggests that patients who are discharged home have satisfactory outcomes during support and following heart transplantation. METHODS: A retrospective review of 24 patients implanted with an LVAD between October 2001 and December 2006 was performed. Nineteen patients received a device as a bridge to transplantation and five received a device as destination therapy. Postoperative follow-up was performed routinely in the heart function/LVAD clinic at the Toronto General Hospital (Toronto, Ontario) and all adverse events were recorded. RESULTS: The majority of patients were men, with a mean age of 44 years and a diagnosis of dilated cardiomyopathy (62%). Seventeen patients (71%) were discharged home on support; one died, 14 were transplanted, one was explanted and one patient remains on support in the community. Post-transplant survival was 93% in patients discharged home compared with 40% transplanted during their hospital stay. Outpatients spent 56% of their overall support time at home, with only 12 readmissions totalling 120 patient days. CONCLUSIONS: LVAD patients can be safely managed in the community. Patients who are discharged home experience better outcomes in both pre- and post-transplant survival. Successful outpatient management provides a strong foundation for the establishment of destination therapy within mechanical circulatory support programs in Canada.

Quantifying the regional frequency variation in ventricular fibrillation (VF) may lead to focal strategies in treating human VF. We hypothesized that during human VF there are quantifiable regional frequency variations in the ventricles and they relate to underlying fixed myocardial substrate. In eight myopathic human hearts, we studied 35 VF episodes. The electrograms during VF were acquired simultaneously from the epicardium and endocardium using 2 electrode arrays each consisting of 112 electrodes. Regional characterization was performed using a ratio parameter derived from the dominant frequency analysis of the electrograms. The findings were related to the anatomical substrate using bipolar voltage maps. The results of the analysis indicate that LV had a larger dominant frequency (DF) span than RV (p=0.0111) while there was no significant difference (p=0.1488) in the DF span between LV freewall (FW) and septum (SE). Correlation of areas of abnormal myocardium with the dominant frequency feature matched only in 50% of the cases indicating that ion channel heterogeneity and time-varying physiological factors may play an important role in maintaining VF.

Prosthetic heart valve dysfunction due to thrombus or pannus formation can be a life-threatening complication. The present report describes a 47-year-old woman who developed valvular cardiomyopathy after chorda-sparing mitral valve replacement, and subsequently underwent heart transplantation for progressive heart failure. The explanted mitral valve prosthesis showed significant thrombus and pannus leading to reduced leaflet mobility and valvular stenosis. The present report illustrates the role of the subvalvular apparatus and pannus in prosthesis dysfunction.

Spontaneous coronary artery dissection remains a rare but important cause of acute coronary syndromes. Presentation depends on the extent of the dissection, the vessels involved and the rate of its development, and can encompass the entire spectrum of coronary syndromes, with some patients being asymptomatic and others presenting with angina, non-ST segment elevation myocardial infarction, ST-elevation myocardial infarction and sudden cardiac death. The authors describe a 33-year-old pregnant woman who presented with a non-ST segment elevation myocardial infarction secondary to a spontaneous dissection of the left main coronary artery.

Primary pulmonary artery neoplasms are rare and lethal. Those involving the pulmonary valve are even rarer with only a few reported cases in the literature. The poor prognosis of these neoplasms, despite attempted multimodal therapy, is largely related to delay and difficulty in diagnosis. The case of a 53-year-old woman is described who within one month of suddenly developing shortness of breath was found to have a mass arising from the pulmonary valve and extending through the pulmonary vasculature, requiring extensive surgical resection. She died two weeks postoperatively. The morphological findings of this primary pulmonary artery sarcoma are presented. Diagnosis, treatment, prognosis and literature are reviewed, and consideration of this tumour in the differential diagnosis of other pulmonary diseases is emphasized.

The incidence of breast cancer in the city of Palermo and its Province was investigated. The cancer rate was higher in the city of Palermo (100.8/100,000/year), a great southern urban area, than in the 81 municipalities of the Province (79.2/100,000/year). Rates were also compared with those in other geographic areas of Italy, showing a smaller than expected negative north-south gradient in incidence, especially in the young age group, as shown by the cumulative risk observed in the 0-54-year-old group. These findings confirm the role of recent life style changes in the cancer risk distribution.

Preliminary evidence from a case control study of healthy postmenopausal women living in Palermo, Sicily, is presented to investigate the potential impact of a traditional Mediterranean diet on the risk of developing breast cancer. Of the 230 women who fulfilled specific eligibility criteria, 115 were enrolled in the study based on serum testosterone values equal to or greater than the median population value (0.14 microg/ml). Women were then individually randomized into a diet intervention (n = 58) and a control (n = 55) group. Women in the intervention group attended a weekly "cooking course" for 1 year, being trained by professional chefs in the correct use of the natural ingredients of the traditional Mediterranean diet, including whole cereals, legumes, seeds, fish, cruciferous vegetables, and many others. The intervention group was subsequently instructed to follow the learned diet at home, while the control group was only advised to increase the consumption of fruits and vegetables, as recommended by WHO. The following measures were taken at the beginning, middle, and end of the study: (a) fasting blood and 12-hour urine samples to assay defined hormonal endpoints; (b) height, weight, and circumference of the waist and hip; and (c) a food frequency and computerized 24-hour dietary recall questionnaire. After 1 year, both the control and the intervention groups showed satisfactory compliance rates (81 and 85%, respectively). In addition, preliminary results so far obtained reveal an unequivocal trend towards weight loss, a strong reduction in cholesterol levels, and a psychophysical feeling of well-being by women adopting the Mediterranean diet. The study is currently ongoing to verify the association of changes in serum and urine hormone levels and breast cancer risk in the intervention group.

OBJECTIVE: To compare the incidence and pattern of onset of postoperative atrial fibrillation (AF) in patients undergoing coronary artery bypass graft (CABG) surgery with and without cardiopulmonary bypass (CPB). DESIGN: Retrospective, cohort-controlled study. SETTING: University hospital and tertiary referral center. PARTICIPANTS: A group of 108 consecutive patients who underwent primary off-pump coronary artery bypass (OP-CAB) surgery and a control group of 100 patients who underwent CABG surgery with CPB. All patients underwent surgery between January and September 1999. INTERVENTIONS: Patients in the OP-CAB surgery group were operated on by either of 2 surgeons. The CABG surgery group was drawn from the general pool of patients operated on by 1 of 10 surgeons. All patients underwent median sternotomy and received standard anesthesia and intensive care unit management for this institution. MEASUREMENTS AND MAIN RESULTS: Data from 99 OP-CAB surgery patients (data incomplete in 9 patients) were compared with data from 100 CABG surgery patients. General demographics were similar except the CABG surgery group received a higher mean number of distal anastomoses (3.3 v 3.0; p = 0.028) The incidence of AF was similar in both groups (OP-CAB surgery, 25% v CABG surgery, 18%; p = 0.228). The peak incidence of AF was postoperative day 2 in both groups. The median hospital length of stay was increased in patients developing AF. CONCLUSION: Avoiding CPB does not seem to reduce the incidence of postoperative AF in CABG surgery. The similar time distribution of onset of AF in OP-CAB surgery patients and CABG surgery patients may point toward a common cause.
