RESUMEN
Marfan syndrome (MFS) is a systemic connective tissue disease that commonly and most severely affects the ocular, skeletal, and cardiovascular systems. The aim of the manuscript is to review the aortic involvement and complications in MFS, including aortal dissection, thoracic aortic aneurysm, abdominal aortic aneurysm, and acute aortic syndrome. Dissecting thoracic aortic aneurysm and progressing aortic root enlargement are the major causes of MFS morbidity and mortality. Guidelines on aortic disease endorsed by the American College of Cardiology, and the American Heart Association recommend the measurement of the external and internal aortic diameters perpendicular to the axis of blood flow when Computed Tomography, or Magnetic Resonance Imaging, or Cardiac Echography are performed. The pathophysiology, diagnosis, prevention, and medical and surgical treatments of MFS associated with aortic complications are reported in this narrative review. Development and strengthening of centers specialized in cardiovascular diseases and MFS, together with an improvement in the knowledge of its pathogenesis through genetics and proteomics investigations, can ameliorate the prognosis of this disease.

OBJECTIVE: The aim of this study was to evaluate New York Heart Association (NYHA) class and systolic pulmonary artery pressure (sPAP) as survival predictors in major interstitial lung diseases (ILD) including idiopathic pulmonary fibrosis (IPF), non-specific interstitial pneumonia (NSIP) and hypersensitivity pneumonitis (HP) and in other ILD like granulomatosis with polyangiitis (GPA). PATIENTS AND METHODS: We analyzed survival, NYHA class, sPAP, and Octreoscan uptake index (UI) in 104 ILD patients (59 IPF, 19 NSIP, 10 HP and 16 GPA; median age 60.5 years) all referred to a single centre. RESULTS: Median survival was 68 months, with 1- and 2-year survival of 91% and 78%, respectively. Survival was lower among IPF and NSIP vs. HP and GPA patients (p=0.01). NYHA class 3-4 was more frequent among IPF (76.3%) vs. NSIP patients (31.6%; p<0.001). HP and GPA had NYHA class 1-2. NYHA class was negatively associated with survival (class 1=90.3 months vs. class 3=18.3 months and class 4=5.1 months; p=0.001). sPAP was >55 mmHg in 76.3% of patients with IPF and 35-55 mmHg in 63.2% of patients with NSIP. Patients with HP and GPA had sPAP < 55 mmHg. Among patients with IPF, NYHA and sPAP were negatively associated with survival (p<0.01) both showed a parallel trend. High-resolution computed tomography and survival were worse among IPF and NSIP vs. HP and GPA patients (p<0.001). Octreoscan UI was <10, 10-12, and >12 in IPF, NSIP, HP and GPA, respectively. Octreoscan UI was negatively associated with survival (p=0.002). CONCLUSIONS: NYHA class and sPAP are comparable ILD survival predictors. NYHA class is correlated with worse prognosis for IPF and NSIP vs. HP and GPA patients.

Stem cells transplantation after acute myocardial infarction (AMI) has been claimed to restore cardiac function. However, this therapy is still restricted to experimental studies and clinical trials. Early un-blinded studies suggested a benefit from stem cell therapy following AMI. More recent blinded randomized trials have produced mixed results and, notably, the last largest pan-European clinical trial showed the inconclusive results. Furthermore, mechanisms of potential benefit remain uncertain. This review analytically evaluates 34 blinded and un-blinded clinical trials comprising 3142 patients and is aimed to: (1) identify the pros and cons of stem cell therapy up to a 6-month follow-up after AMI comparing benefit or no effectiveness reported in clinical trials; (2) provide useful information for planning future clinical programs of cardiac stem cell therapy.

OBJECTIVE: Mortality risk factors as forced vital capacity, diffuse lung capacity for carbon monoxide, and 6-minutes' walk test were studied in clinical trials monitoring patients affected by interstitial lung diseases (ILD). However, these parameters showed scarce accuracy. Our aim was to identify New York Heart Association (NHYA) class, in association with high resolution computed tomography (HRCT) and somatostatin receptor scintigraphy (Octreoscan), as a prognostic mortality risk factor in ILD patients. PATIENTS AND METHODS: Study population comprised 128 ILD patients (78 Males and 50 Females). Histological diagnosis was usual interstitial pneumonia (UIP), non-specific interstitial pneumonia (NSIP) and granulomatous lung disease in 59, 19 and 50 patients, respectively. Patients were monitored by NYHA class, HRCT and Octreoscan at baseline and every 3 years up to a 10-year follow up. Overall survival was calculated from the date of diagnosis until death or last follow-up update. Statistical analysis was performed using Kaplan-Meier, log-rank test (LRT), multivariate analysis with Cox proportional hazard regression model, and log-likelihood ratio test. RESULTS: Overall median survival was 89.3 months (7.4 years) with the poorer survival rate observed in UIP patients. NYHA class came out as a reliable prognostic mortality risk factor in each group of patients and prognosis was progressively worse with NYHA class increase (LRT p<0.001). A strong correlation was found between NYHA class and age, CT-score, and Octreoscan in UIP patients (p<0.001). CONCLUSIONS: The determination of NYHA class can therefore be recommended as an additional prognostic mortality risk factor in ILD patients.

Understanding the risks of atherosclerotic cardiovascular disease (CVD) allows for better patient education and management. Multiple risk models have been validated in large patient populations and provide insights into the risks associated with CVD. When assessing such risks, we suggest using a model that predicts myocardial infarction, cardiovascular death, and/or cerebrovascular events. In this review, we analyze several risk models and stratify the risks associated with CVD. We suggest that appropriate profiling of patients at-risk of CVD will lead to better physician recognition and treatment of modifiable risk factors, appropriate application of ATP III treatment for hyperlipidemia, and achieving optimal blood pressure control.

Several authors proposed the stage at diagnosis and some histopathological features as prognostic factors of bronchial carcinoids. However, since large tumour diameters or nodal metastases are frequently associated to aggressive histology, their prognostic role is unclear. To investigate the relationships between the clinicopathological parameters at diagnosis and outcome, 21 patients were analysed. Overall 26% of the radically resected patients recurred. Recurrences and disease-specific mortality were related to atypical histology and, only in cases with typical histology, to the presence of hilar or mediastinal lymph node metastases. These prognostic factors were valuable independently of the size of the primary tumour, that was remarkably homogeneous, always less than 3 cm, thus not predictive of recurrence. Moreover we evaluated the role of somatostatin receptor scintigraphy, a diagnostic tool only preliminary studied in this field. Scintigraphy with 111In-octreotide revealed the primary tumours at diagnosis (8/8), the increase in tumour size in two unresected patients, and all the cases of recurrent or metastatic disease (5/11), sometimes before the appearance of symptoms. These results suggest the usefulness of histology and nodal status as prognostic factors in clinical practice. Somatostatin receptor scintigraphy turns out to be a powerful diagnostic tool, for an accurate staging and an early diagnosis of recurrence in bronchial carcinoids.
