[The graduate school of medicine and palliative care: good news, but it's still not enough.] / La Scuola di specializzazione in medicina e cure palliative: una bella notizia, ma non è ancora abbastanza.

The recent establishment of palliative care and medicine as a medical specialty to be taught in postgraduate courses starting from the 2021/2022 academic year in Italy is certainly good news. Some doubts arise, anyway, if the academic programs will be limited to the postgraduate area instead of involving every university in the undergraduate courses. The risk is to maintain the reductionism of future physicians receiving a kind of education centered on the biomedical paradigm only. Since at least thirty years we know that there should not be a definite time marking a clear break between previous active treatments for the disease and subsequent palliative ones. Mainly in very old people affected by multiple chronic disorders a simultaneous presence of both forms of treatment should be scheduled, with increasing weight of palliation as the disease progresses and the probability of responding to active treatments becomes less and less. Unfortunately the reality of assistance in the last thirty days of life of patients suffering from cancer and/or chronic heart or lung diseases is increasingly centered on hospital settings, while the proportion of patients who are referred for hospice/palliative care in the last month of life is marginal, especially for non-cancer patients. We are going on with a health system that responds to the needs of the chronicities with the structures and pathways that are suitable for acute care: a completely different model would be needed. For over ten years palliative care in Italy has a specific regulatory reference such as that of law 38/2010, reaffirmed by the most recent law 219/2017: yet, although training is expressly provided for in these laws, we are still far from having made it, except for some sporadic cases. Now it seems that we are about to accomplish such provisions, even if starting from the roof instead of the foundations; as palliative care means multiprofessional and multidisciplinary teams a specific training program dedicated also to nurses, psychologists and physiotherapists is mandatory.

[Chronic diseases and risk of symptomatic COVID-19: results of a case-population study on a sample of patients in the Local Health Unit 'Toscana Centro' (Tuscany Region, Central Italy)]. / Malattie croniche e rischio di ammalarsi di COVID-19 sintomatica: risultati di uno studio case-population su un campione di casi in AUSL Toscana Centro.

BACKGROUND: the COVID-19 pandemic represents a challenge for health systems around the world, with just under 10,000 cases in Tuscany Region (Central Italy) and about 4,500 in the Local Health Unit (LHU) 'Toscana Centro', updated on 11 May 2020. The risk factors reported are several, including age, being male, and some chronic diseases such as hypertension, diabetes, respiratory and cardiovascular diseases. However, the relative importance of chronic diseases is still to be explored. OBJECTIVES: to evaluate the role of chronic diseases on the risk to develop clinically evident (at least mild symptomatic) forms of SARS-CoV-2 infection in the population of the LHU Toscana Centro. DESIGN: case-population study. SETTING AND PARTICIPANTS: 'case' is a subject with SARS-CoV-2 positive swab with at least mild clinical status, who lives in the LHU Toscana Centro area; 'controls' are all people residing in the LHU Toscana Centro area at 1 January 2020. People aged under 30 and patients living in nursing care homes are excluded from the analysis. MAIN OUTCOME MEASURES: the analysis assesses the effect of gender, age, neoplasm, and the main chronic diseases on the onset of an infection with at least mild symptoms by calculating odds ratios (OR) by multivariate logistic regression models (to produce adjusted OR by potential confounders). RESULTS: among the 1,840 cases, compared to the general population, the presence of males and over-60-year-old people is greater. Almost all the considered chronic diseases are more frequent among the cases, compared to the general population. A chronic patient has a 68% greater risk to be positive with at least mild symptoms. Many of the considered diseases show an effect on the risk of getting COVID-19 in a symptomatic form, which remains even adjusting by other comorbidities. The main ones include heart failure, psychiatric disorders, Parkinson's disease, and rheumatic diseases. CONCLUSIONS: these results confirm evidence already shown in other studies on COVID-19 patients and add information on the chronic diseases attributable risk in the population, referred to the symptomatic forms and adjusted by age, gender or the possible copresence of more diseases. These risk estimates should guide prevention interventions by health services in order to protect the chronic patients affected by the pathologies most at risk.

Diagnosis-related differences in the quality of end-of-life care: A comparison between cancer and non-cancer patients.

BACKGROUND: Cancer, chronic heart failure (CHF), and chronic obstructive pulmonary disease (COPD) in the advanced stages have similar symptom burdens and survival rates. Despite these similarities, the majority of the attention directed to improving the quality of end-of-life (EOL) care has focused on cancer. AIM: To assess the extent to which the quality of EOL care received by cancer, CHF, and COPD patients in the last month of life is diagnosis-sensitive. METHODS: This is a retrospective observational study based on administrative data. The study population includes all Tuscany region residents aged 18 years or older who died with a clinical history of cancer, CHF, or COPD. Decedents were categorized into two mutually exclusive diagnosis categories: cancer (CA) and cardiopulmonary failure (CPF). Several EOL care quality outcome measures were adopted. Multivariable generalized linear model for each outcome were performed. RESULTS: The sample included 30,217 decedents. CPF patients were about 1.5 times more likely than cancer patients to die in an acute care hospital (RR 1.59, 95% C.I.: 1.54-1.63). CPF patients were more likely to be hospitalized or admitted to the emergency department (RR 1.09, 95% C.I.: 1.07-1.10; RR 1.15, 95% C.I.: 1.13-1.18, respectively) and less likely to use hospice services (RR 0.08, 95% C.I.: 0.07-0.09) than cancer patients in the last month of life. CPF patients had a four- and two-fold higher risk of intensive care unit admission or of undergoing life-sustaining treatments, respectively, than cancer patients (RR 3.71, 95% C.I.: 3.40-4.04; RR 2.43, 95% C.I.: 2.27-2.60, respectively). CONCLUSION: The study has highlighted the presence of significant differences in the quality of EOL care received in the last month of life by COPD and CHF compared with cancer patients. Further studies are needed to better elucidate the extent and the avoidability of these diagnosis-related differences in the quality of EOL care.

Clinical outcome, valve dysfunction, and progressive aortic dilation in a pediatric population with isolated bicuspid aortic valve.

The aim of this study was to explore the medium-term clinical outcome and the risk of progression of aortic valve disease and aortic dilation in pediatric patients with isolated bicuspid aortic valve (BAV). 179 pediatric patients with isolated BAV were prospectively followed from January 1995 to December 2010. Patients with severe valve dysfunction at baseline were excluded. Clinical outcome included cardiac death, infective endocarditis, aortic complications, cardiac surgery and percutaneous valvuloplasty. Echocardiographic endpoints were: progression of aortic stenosis (AS) or regurgitation (AR) and progressive aortic enlargement at different levels of the aortic root, evaluated as z-score. The median age at diagnosis was 7.8 [2.7-12.0] years. After a median followup of 5.4 [2.3-9.2] years, all patients were alive. The clinical endpoint occurred in 4 (2.2 %) patients (0.41 events per 100 patient-years). A progression of AS and AR was observed in 9 (5.0 %) and 29 (16.2 %) patients, respectively. The z-scores at the end of follow-up were not significantly different from baseline at the annulus, Valsalva sinuses and sinotubular junction, whereas a slight increase was observed at the level of the ascending aorta (1.9 vs 1.5, p = 0.046). Significant progressive aortic dilation occurred in a minority of patients (10.6, 5.6, 9.5, and 19.0 % respectively). The clinical outcome in pediatric patients with isolated BAV is favourable and the progression of aortic valve dysfunction and aortic dilation is relatively slow. These findings may be taken into account to better guide risk assessment and clinical follow-up in these patients.

Subclavian steal syndrome presenting as recurrent pulmonary oedema associated with acute left ventricular diastolic dysfunction.

Subclavian steal syndrome typically presents as angina in patients with internal mammary artery grafts. Atypical clinical presentations have been rarely described. We report an unusual case of subclavian steal syndrome presenting as pulmonary oedema with acute left ventricular diastolic dysfunction and preserved ejection fraction in a patient with internal mammary artery graft and severe stenosis of the proximal left subclavian artery. After successful angioplasty and stenting of subclavian artery, the patient remained asymptomatic for six months, but then experienced acute diastolic dysfunction and recurrent pulmonary oedema associated with critical subclavian in-stent restenosis with stent deformation. This report points out that, in patients with internal mammary-to-LAD grafts, subclavian steal syndrome may present as acute left ventricular diastolic dysfunction and pulmonary oedema even in the presence of normal ejection fraction.

Acute inflammatory bowel disease complicating chronic alcoholism and mimicking carcinoid syndrome.

We report the case of a woman with a history of chronic alcohol abuse who was hospitalized with diarrhea, severe hypokalemia refractory to potassium infusion, nausea, vomiting, abdominal pain, alternations of high blood pressure with phases of hypotension, irritability and increased urinary 5-hydroxyindoleacetic acid and cortisol. Although carcinoid syndrome was hypothesized, abdominal computed tomography and colonoscopy showed non-specific inflammatory bowel disease with severe colic wall thickening, and multiple colic biopsies confirmed non-specific inflammation with no evidence of carcinoid cells. During the following days diarrhea slowly decreased and the patient's condition progressively improved. One year after stopping alcohol consumption, the patient was asymptomatic and serum potassium was normal. Chronic alcohol exposure is known to have several deleterious effects on the intestinal mucosa and can favor and sustain local inflammation. Chronic alcohol intake may also be associated with high blood pressure, behavior disorders, abnormalities in blood pressure regulation with episodes of hypotension during hospitalization due to impaired baroreflex sensitivity in the context of an alcohol withdrawal syndrome, increased urinary 5-hydroxyindoleacetic acid as a result of malabsorption syndrome, and increased urinary cortisol as a result of hypothalamic-pituitary-adrenal axis dysregulation. These considerations, together with the regression of symptoms and normalization of potassium levels after stopping alcohol consumption, suggest the intriguing possibility of a alcohol-related acute inflammatory bowel disease mimicking carcinoid syndrome.

Dilated cardiomyopathy and inclusion body myositis.

Inclusion body myositis (IBM) is the most common inflammatory myopathy after 50 years of age. In contrast to polymyositis and dermatomyositis, in which cardiac involvement is relatively common, current evidences indicate that IBM is not associated with cardiac disease. We report the case of a patient with biopsy-proven IBM who developed heart failure and major ventricular arrhythmias secondary to dilated cardiomyopathy few months after the clinical onset of IBM, and in whom no pathophysiologic causes explaining cardiac enlargement and dysfunction were found by laboratory and instrumental investigations. The hypothesis of a pathophysiologic association between the two conditions is discussed.

Isolated papillary muscle rupture complicating acute pancreatitis.

Papillary muscle rupture in the absence of coronary stenoses is a rare event. An isolated infarction of the papillary muscle is involved in most cases, but the pathogenesis is still debated. We describe an anterolateral papillary muscle rupture complicating acute pancreatitis in a patient without significant coronary stenoses and with evidence of coronary spasm. This suggests that an increased susceptibility to coronary spasm and thrombosis, triggered by an acute systemic inflammatory response, may represent a mechanism of selective papillary muscle infarction.

The role of N-terminal PRO-brain natriuretic peptide and echocardiography for screening asymptomatic left ventricular dysfunction in a population at high risk for heart failure. The PROBE-HF study.

BACKGROUND: Screening for asymptomatic left ventricular dysfunction (ALVD) in subjects at risk for heart failure (HF) can affect clinical management. The aim of the present study is to examine the role of NT-pro BNP in the diagnosis of ALVD in subjects with hypertension and diabetes from primary care. METHODS AND RESULTS: A total of 1012 subjects with hypertension and/or diabetes and no symptoms or signs of HF were assessed by B-type natriuretic peptide (NT-proBNP) assay and echocardiography. Diastolic dysfunction was present in 368/1012 subjects (36.4%): 327 (32.4%) with mild diastolic dysfunction and 41 (4%) with a moderate-to-severe diastolic dysfunction. Systolic dysfunction was present in 11/1012 (1.1%). NT-proBNP levels were 170 +/- 206 and 859 +/- 661 pg/mL, respectively, in diastolic and systolic dysfunction and 92 +/- 169 in normal subjects (P < .0001). Pooling moderate-to-severe diastolic with systolic dysfunction, a total of 52 subjects (5.1 %) were obtained: best cutoff value of NT-proBNP was 125 pg/mL (males <67 years: sensitivity [Sens] 87.5%, specificity [Spec] 92.7%, negative predictive value [NPV] 99.5%, positive predictive value [PPV] 33.3%; females <67 years: Sens 100%, Spec 84.1%, NPV 100%, PPV 33.3%; males >or=67 years: Sens 100%, Spec 77.1%, NPV 100%, PPV 32.5%; females >or=67 years: Sens 100%, Spec 59.9%, NPV 100%, PPV 23%). CONCLUSIONS: The prevalence of ALVD in subjects at risk for HF is 5.1%. Because of its excellent NPV, NT-proBNP can be used by general practitioners to rule out ALVD in hypertensive or diabetic patients.

[Mitral valve prolapse]. / Il prolasso valvolare mitralico.

Mitral valve prolapse (MVP) is still a clinical challenging problem. In this report, we review the main characteristics of this entity. Epidemiology of MVP, which relies on the diagnostic criteria adopted, and the incidence of complications, both arrhythmic and structural, are influenced by the characteristics of the population studied, which may lead to bias in data interpretation. Even the definition of MVP may differ according to the cardiologist's or cardiac surgeon's point of view. Usually, cardiologists define MVP as the protrusion of all or part of the mitral leaflets into the left atrium, independent of maintenance of coaptation. Therefore, using this definition, mitral regurgitation is considered as a complication rather than a diagnostic criterion. Arrhythmias, either supraventricular or ventricular, are other possible complications, mostly not life-threatening and associated with myxomatous degeneration of the valve. Diagnosis of MVP is based on echocardiography, which provides detailed anatomic and functional evaluation of the affected valve. Leaflet thickness and motion as well as presence and severity of mitral regurgitation can be assessed, with important diagnostic and prognostic implications. Echocardiographic evaluation of the mitral valve requires a systematic approach in order to define the leaflet/scallop involved and the mechanisms of mitral regurgitation. To this aim, three-dimensional reconstruction may add further insights into objective rendering of mitral valve pathology. Finally, surgical timing in mitral regurgitation due to MVP is an evolving issue and the likelihood of surgical repair is a crucial factor in the optimal timing of surgical intervention, especially in asymptomatic patients with severe mitral regurgitation.

Effect of statins on the progression of bioprosthetic aortic valve degeneration.

To date, there is no proved medical therapy able to significantly reduce the degenerative process of biologic prosthetic aortic valves. It has recently been suggested that statins may reduce the progression of native aortic valve stenosis. We examined the effect of statin treatment on bioprosthetic aortic valve degeneration and found a beneficial effect of statins in slowing bioprosthetic degeneration.

Therapeutic implications of contractile reserve elicited by dobutamine echocardiography in symptomatic, low-gradient aortic stenosis.

BACKGROUND: In patients with heart failure, poor ejection fraction and estimated severe aortic stenosis because of a reduced aortic valve area (AVA) and low gradients, dobutamine echocardiography (DE) was proposed to distinguish afterload mismatch from primary left ventricular dysfunction. In this setting the feasibility and safety of DE and the outcome following management based on DE results were investigated. METHODS: Forty-eight patients (mean age 73 +/- 9 years; 79% males; AVA 0.7 +/- 0.2 cm2; mean aortic gradient 22 +/- 6 mmHg; ejection fraction 0.28 +/- 0.07; NYHA functional class 2.9 +/- 0.8) underwent DE and were followed up for 24 +/- 21 months. Aortic valve replacement (AVR) was offered to patients with left ventricular contractile reserve (ejection fraction increase > or = 30% at peak DE) and fixed aortic stenosis (AVA increase < or = 0.25 cm2). RESULTS: DE elicited a left ventricular contractile reserve in 38 patients (79%). Among these, fixed aortic stenosis was present in 28 patients, among whom 19 underwent AVR and 9 declined surgery. The 20 patients without contractile reserve or with relative stenosis (AVA increase > 0.25 cm2) were not considered eligible for surgery. During follow-up, 23 cardiovascular deaths occurred: 2/19 among operated patients, 7/9 among patients who declined surgery and 14/20 among non-eligible patients. Patients with AVR showed a significantly more favorable outcome and improved functional status as compared to the other two groups (NYHA class 1.2 +/- 0.4 vs 2.7 +/- 0.6 at baseline; p < 0.001). Conversely, non-surgical management was the strongest independent predictor of an adverse outcome (relative risk 3.6, 95% confidence interval 1.8-7.3; p < 0.0001). CONCLUSIONS: In patients with heart failure and estimated severe aortic stenosis, DE could identify a subgroup with a left ventricular contractile reserve and fixed aortic stenosis who gained great benefit from AVR. The clinical outcome of patients who were not operated upon was unfavorable.

[Preoperative cardiovascular assessment in non-cardiac surgery: the role of non-invasive procedures]. / Valutazione cardiovascolare preoperatoria nella chirurgia non cardiaca: il ruolo delle indagini strumentali non invasive.

The aim of cardiovascular preoperative evaluation in non-cardiac surgery is to assess the patient's current cardiovascular status, to detect unknown diseases, to make recommendations concerning the medical management of the patient in the peri- and postoperative period, to plan the surgical strategy or, in some cases, to postpone non-cardiac surgery until the cardiac condition is corrected or stabilized; rarely, cardiovascular evaluation may result in an absolute contraindication for non-cardiac surgery. The basic clinical evaluation obtained by history, physical examination and review of the ECG usually provides enough data to estimate the cardiac risk. Patient's risk factors (unstable coronary syndromes, congestive heart failure, life-threatening arrhythmias, severe valvular heart diseases) and the type and setting of surgery are to be considered together with the clinical evaluation. Additional non-invasive tests may be recommended to evaluate left ventricular function and the presence of myocardial ischemia only if expected data will eventually result in changing the surgical procedure or perioperative management. Echocardiography is particularly useful in patients with major risk factors whereas exercise stress test is able to assess the patient's functional capacity or to identify silent myocardial ischemia or significant arrhythmias. The overall goal of cardiac assessment should be a consideration of both the impending surgery and the long-term cardiac risk independent of the decision to go to surgery. It is almost never appropriate to recommend coronary bypass surgery or other invasive interventions such as coronary angioplasty in an attempt to reduce the risk of non-cardiac surgery when they would not otherwise be indicated.

[Patterns of information and informed consent procedures. Study of the Ethical Commission of the ANMCO]. / Modalità di informazione ed acquisizione del consenso informato. Indiagine della Commissione Etica dell'ANMCO.

A survey on patterns of information and informed consent procedures during daily clinical practice has been performed by the Ethical Commission of ANMCO. A structured questionnaire (38 questions) was sent to the 653 cardiological units of the National Health Service in Italy. Four hundred and eighty (73.5%) were received. The following variables were considered to evaluate differences in the answers from the various cardiological units: geographical site, presence or absence of an in-patient department, a cath-lab, and of cardiac surgery facilities. Independent predictors of returning questionnaires were: geographical site (Northern Italy vs Central and Southern) and the presence of a cath-lab. Informed consent forms were provided in 53% of instances, while in 40% a free comment about the topic of informed consent was sent. Statistically significant differences in the answers were found about physicians' and nurses' role, ways of information, qualitative and quantitative risk estimates, other persons' role, models of consent forms and procedures of obtaining consent. Free comments and informed consent forms did not allow a statistical analysis. However, they still provided sufficient material to identify specific patterns of how cardiologists deal with the informed consent process. The distinction between the two phases of information and consent was rarely clear. Information or educational material was often mixed with consent forms. While some still showed a paternalistic approach, or else considered informed consent as a formal act, others demonstrated a deep understanding of the significance of the concept of informed consent. A widespread need of guidelines and standard patterns resulted.
