Barriers and incentives for Italian paediatricians to become smoking cessation promoters: a GARD-Italy Demonstration Project

2020

Background: Paediatricians rarely devote any time to screening and treatment for parental tobacco use. The present project is part of a Global Alliance against Chronic Respiratory Diseases (GARD)-Italy Demonstration Project, aimed to increase the skills of primary care physicians and paediatricians as "promoter of smoking cessation". The aims of this study were: (I) to identify latent classes of barriers and incentives for smoking cessation counseling among paediatricians using latent class analysis (LCA); (II) to investigate risk factors for inclusion into the identified classes. Methods: In 2018, 1,500 Italian paediatricians were invited to complete an online survey on passive smoke expos…

Reoperation and the centrifugal pump?

1992

Postperfusion syndrome is still a problem in long cardiac operations using extracorporeal circulation (ECC). To evaluate whether or not centrifugal blood pumping during open heart surgery is beneficial, a randomized, prospective study was undertaken of 50 consecutive patients undergoing elective coronary artery bypass grafting. The patients were divided into two groups of 25 each. In group 1 a centrifugal pump (Biomedicus) was used as arterial blood pump, while in group 2 a roller pump (Stockert) was used. The two groups did not differ significantly and the number of variables during surgery was kept low (identical perfusion set, two surgeons, minimal cardiotomy suction). The parameters stu…

Neutrophil Adherence to Activated Saphenous Vein and Mammary Endothelium After Graft Preparation

2005

Interaction of circulating leukocytes and vascular endothelium plays an important role in vasoconstriction, endothelial dysfunction, and vascular injury. Dilation procedures of grafts before coronary artery bypass graft surgery might lead to vascular injury and subsequent bypass graft disease.We analyzed in vitro the adherence of fluorescence-labeled polymorphonuclear neutrophils (PMNs) to endothelium of human saphenous vein grafts or internal mammary artery grafts after stimulation with thrombin (0.5 to 2 U/mL) or dilating procedures. Furthermore, we investigated endothelial function of prepared grafts.Thrombin stimulation resulted in a dose-dependent increase of PMN adherence to the endot…

Extracorporeal circulation activates endothelial nitric oxide synthase in erythrocytes.

2007

Background Extracorporeal circulation used in cardiopulmonary bypass and hemodialysis is often associated with severe hypotension, which is an important predictor for mortality and morbidity. One pathophysiological hypothesis includes nitric oxide (NO) generation. Recently, a functional NO synthase (endothelial type NO synthase [eNOS]), was found to be expressed in human red blood cells. However, to date, activation of red blood cell eNOS has not been shown. We hypothesized that eNOS in circulating red blood cells might be activated during extracorporeal circulation and thus contribute to hypotension through vasodilation upon NO release. Methods We collected blood samples from 28 patients e…

Early LVAD Implantation in a Patient with Left Ventricular Failure after Aortic Dissection with Left Main Stem Involvement

2018

Background: Coronary involvement in aortic dissection heralds a poor outcome. Involvement of the left main stem may lead to left ventricular (LV) failure requiring mechanical circulatory support. Case Report: A staged approach was applied in a 24-year-old female who suffered extensive infarction due to aortic dissection with left main stem involvement. After replacement of the ascending aorta and grafting of the left internal thoracic artery to the left anterior descending artery following a failed attempt at reconstruction of the left coronary ostium, she failed to wean from cardiopulmonary bypass (CPB) and underwent implantation of an extracorporeal life support (ECLS) system as a bridge …

T-shaped Transseptal Approach for Mitral Valve Surgery.

2020

AbstractWe present a T-shaped transseptal approach for mitral valve surgery that makes adequate exposure possible under challenging anatomic and surgical circumstances, hence eliminating the need for forceful retraction on potentially fragile tissues. Particularly suited for patients with complex mitral pathology, it also facilitates juxta-annular transseptal right atrial anchoring, especially in cases of endocarditic anterior mitral annular destruction.

Smoke exposure as a risk factor for asthma in childhood: A review of current evidence

2014

Asthma is a common chronic multifactorial disease that affects >300 million people worldwide. Outdoor and indoor pollution exposure has been associated with respiratory health effects in adults and children. Smoking still represents a huge public health problem and millions of children suffer the detrimental effects of passive smoke exposure. This study was designed to review the current evidences on exposure to passive smoke as a risk factor for asthma onset in childhood. A review of the most recent studies on this topic was undertaken to provide evidence about the magnitude of the effect of passive smoking on the risk of incidence of asthma in children. The effects of passive smoking are …

Third-hand smoke exposure and health hazards in children

2013

Smoking still represents a huge public health problem. Millions of children suffer the detrimental effects of passive smoking. An increasing number of countries have recently issued laws to regulate smoking in public places. Instead, homes remain a site where children are dangerously exposed to environmental tobacco smoke (ETS). The combination of tobacco smoke pollutants which remain in an indoor environment, the so-called ‘third-hand smoke’ (THS), represent a new concept in the field of tobacco control. THS consists of pollutants that remain on surfaces and in dust after tobacco has been smoked, are re-emitted into the gas-phase, or react with other compounds in the environment to form se…

A review of 507 off-pump coronary bypass patients: a single center experience.

2007

This retrospective study evaluates perioperative results of 'Off-pump' coronary artery bypass surgery (OPCAB) experience in a single center. Five hundred and seven patients were operated (median sternotomy) from 1998 to 2002 using OPCAB. Patient data were registered and risk prediction calculated using the full logistic version of EuroSCORE. Overall, 1091 distal anastomoses were performed and only five (1%) patients required conversion to cardiopulmonary bypass. The predicted mortality was 3.8+/-4.5%, the observed mortality was 2.37%. OPCAB technique has become a standard approach in our department with low mortality and morbidity rates even in treatment of multivessel disease or high-risk …
