Body mass index and baseline platelet count as predictive factors in Merkel cell carcinoma patients treated with avelumab
2023
BackgroundMerkel cell carcinoma (MCC) is a rare and aggressive skin cancer, associated with a worse prognosis. The Immune Checkpoint Inhibitors (ICIs) avelumab and pembrolizumab have been recently approved as first-line treatment in metastatic MCC (mMCC). The clinical observation of improved outcomes in obese patients following treatment with ICIs, known as the “obesity paradox”, has been studied across many types of tumors. Probably due to the rarity of this tumor, data on mMMC patients are lacking.Patients and methodsThis is an observational, hospital-based, study to investigate the role of Body Mass Index (BMI) as predictive biomarker of ICI response in mMCC patients treated with aveluma…
[Diagnosis of coronary microvascualar dysfunction in diabetic patients with cardiac syndrome X: comparison by current methods].
2013
The study population included 208 patients with chest pain and uninjured coronary arteries that we split into two populations: diabetics (72 patients) and non-diabetics (136 patients). We split patients with chest pain and uninjured coronary arteries that had a myocardial scintigraphy into two populations: patients with positive scintigraphy and negative. We calculated, on angiographic images of each patient, stored on suitable digital supports, Timi Frame Count (TFC), Myocardial Blush Grade (MBG) and Total Myocardial Blush Score (TMBS) using the protocol described by Gibson and Yusuf. On the basis of Yusuf's experience we imagined a new index: the Total Timi Frame Count as the sum of the t…
Rare cardiomyopathies: Diagnostic features
2013
Cardiomyopathies (CM) are an important and heterogeneous group of diseases affecting the myocardium. They can induce mechanical and/or electrical disorders and are due to a variety of causes, they frequently are genetic. However, since their high number and their clinical complexity, the identification is still a challenge. Echocardiography is a very useful tool in the assessment of CM. In this review we aim to define the typical clinical features and to discuss the main diagnostic tool, above all echocardiography that can help physicians in the correct assessment of CM.
Self-efficacy and perceived control in the prevention of cardiovascular disease
2010
Desde la Teoría de Acción Planeada (TAP), el objetivo de este trabajo es analizar si la autoeficacia y la percepción de control presentan diferencias predictivas sobre la intención y las conductas preventivas de la enfermedad cardiovascular. La muestra estuvo compuesta por 359 sujetos. Los datos han sido analizados empleando el paquete estadístico EQS 6.1. Los resultados muestran que la autoeficacia influye positiva y significativamente sobre la intención y sobre la conducta, mientras que la percepción de control influye negativa y significativamente sobre la intención de conducta, pero no sobre la conducta preventiva. Este trabajo ha mostrado la conveniencia de distinguir entre autoeficaci…
Renal function and carotid atherosclerosis in adults with no known kidney disease
2017
Abstract Background and aims A high prevalence of atherosclerotic lesions characterizes patients with chronic kidney disease, though there is little data on the relationship between kidney function and atherosclerotic changes in the healthy population or in people with no known renal impairment. The aim of our study was to analyze, in a comprehensive general population with no known kidney disease, the relationship between renal function and subclinical carotid atherosclerotic damage. Methods and results A general real-life population of 611 participants (233 males and 378 females; age ≥18 years) with no known kidney failure was selected for the study. The glomerular filtration rate (GFR) w…
Liraglutide improves metabolic parameters and carotid intima-media thickness in diabetic patients with the metabolic syndrome: an 18-month prospectiv…
2016
Abstract Background Liraglutide, a GLP-1 analogue, exerts several beneficial non-glycemic effects in patients with type-2 diabetes (T2DM), such as those on body weight, blood pressure, plasma lipids and inflammation markers. However, the effects of liraglutide on cardiovascular (CV) risk markers in subjects with the metabolic syndrome (MetS) are still largely unknown. We herein explored its effects on various cardio-metabolic risk markers of the MetS in subjects with T2DM. Methods We performed an 18-month prospective, real-world study. All subjects had T2DM and the MetS based on the AHA/NHLBI criteria. Subjects with a history of a major CV event were excluded. One hundred-twenty-one subject…
High plasma levels of endothelin-1 enhance the predictive value of preclinical atherosclerosis for future cerebrovascular and cardiovascular events: …
2014
BACKGROUND AND PURPOSE: Clinical and experimental evidence suggests that endothelin-1 (Et-1) plays a role in cardiac and vascular disease. In the present study, we investigated the prognostic significance of Et-1 for cerebrovascular and cardiovascular outcome, in a 20-year follow-up. METHODS: We studied 82 originally healthy individuals, referred to our Unit of Cardiovascular Prevention, to evaluate the presence of asymptomatic carotid lesions. We subdivided these individuals into two groups, according to the plasma values of Et-1 (respectively ≤ or >2.7 pg/ml). Traditional cardiovascular risk factors were investigated, and by carotid ultrasound examination, we distinguished between normal …
Relationship between carotid intima-media thickness and non valvular atrial fibrillation type.
2015
OBJECTIVE: Carotid intima-media thickness (cIMT) is a surrogate marker of subclinical atherosclerosis and it is able to predict both coronary and cerebral vascular events. No data exist on the association between cIMT and non valvular atrial fibrillation (NVAF) type. We conduct this study with the aim to analyze the association between abnormal cIMT and NVAF type. METHODS: A cross-sectional study of the "Atrial fibrillation Registry for Ankle-brachial index Prevalence Assessment-Collaborative Italian Study (ARAPACIS)" has been performed. Among 2027 patients enrolled in the ARAPACIS, 673 patients, who underwent carotid ultrasound examination to assess cIMT, were included in the study. RESULT…
Bispectral index changes in carotid surgery.
2010
Intraoperative monitoring of cerebral ischemia with shunting during carotid endarterectomy (CEA) remains controversial. Our objective was to evaluate the sensitivity and specificity of BIS changes during carotid clamping in relation to shunted patients in awake CEA.Eighty CEAs under cervical block were included. There were two patient groups: with clinical signs of cerebral ischemia (shunted patients) and without signs of cerebral ischemia (nonshunted patients). Data were based on bispectral index (BIS) values and neurological monitoring at different surgery time points, with special attention paid during carotid clamping. BIS values were compared between shunted and nonshunted patients. Se…
Impact of preclinical carotid atherosclerosis on global cardiovascular risk stratification and events in a 10-year follow-up: comparison between the …
2019
Background The aim of the study was to compare three widely used algorithms for stratification of the global cardiovascular risk (GCVR): the Framingham Heart Study (FHS) score, the European systemic coronary risk estimation (SCORE) and the Italian 'Progetto Cuore' (heart project) score. It was also investigated how preclinical carotid atherosclerosis (pre-ATS) might influence the incidence and improve the risk prediction of cerebrovascular and cardiovascular events. Methods Subjects (n = 358) without previous history of cardiovascular disease (CVD) were recruited and the GCVR was calculated for each patient. An ultrasound evaluation of the carotid arteries was also performed. Results Accord…
