Patent ductus arteriosus, a persistent communication between the descending thoracic aorta and the pulmonary artery, is one of the most common congenital heart defects. Transcatheter occlusion is an effective alternative to surgery and is currently standard of care for most patients. The authors present the results from a single center after twelve years of experience using this technique.

Retrospective analysis of medical records from all patients referred to a tertiary center for percutaneous ductus closure between January 2006 and September 2018.

A total of 221 patients were referred, with a mean age of 5.5 years-old (16 patients were infants, with the youngest aged four months). A Nit-Occlud® coil was used 139 times (62.9%), an Amplatzer™ duct occluder 79 times (35.7%), and vascular plugs were used three times. Percutaneous closure was achieved in every treated patient, with 1.4% maintaining residual shunting. Although higher overall coil device implantation was noted, duct occluder usage has been greater since 2011. Of all the coils, 55% were either 4x4 or 5x4 mm, and 73% of all Amplatzer duct occluders were either 6x4 or 8x6 mm, which correlates to the majority of patients having a small to moderately sized ductus. No complications were noted during the procedure, with a 1.8% post-procedure complication rate (one device embolization after 48 hours and three cases of loss of arterial pulse).

Percutaneous patent ductus arteriosus closure was safe and effective in this setting, with a low global complication rate and similar outcomes to most equivalent centers.

Bronchial cancer, often diagnosed at a late stage, is the leading cause of cancer death. As early detection could potentially lead to curative treatment, several studies have evaluated low-dose chest CT (LDCT) as a screening method. The main objective of this work is to determine the impact of LDCT screening on overall mortality of a smoking population.

Systematic review of randomised controlled screening trials comparing LDCT with no screening or chest x-ray.

Thirteen randomised controlled trials were identified, seven of which reported mortality results. NSLT showed a significant reduction of 6.7% in overall mortality and 20% in lung cancer mortality after 6.5 years of follow-up. NELSON showed a significant reduction in lung cancer mortality of 24% at 10 years among men. LUSI and MILD showed a reduction in lung cancer mortality of 69% at 8 years among women and 39% at 10 years, respectively.

Screening for bronchial cancer is a complex issue. Clarification is needed regarding the selection of individuals, the definition of a positive result and the attitude towards a suspicious nodule.

In November 2016, France implemented "Mois sans tabac", with the objective of promoting smoking cessation in November for at least one month. This study consisted of (1) the description of the characteristics of smokers registered in the French cessation database during November 2014-2015 compared to November 2016-2017; (2) the comparison of abstinence factors between the two periods.

We used data from CDTnet with 4659 registered adults' smokers who came for a first visit in November from 2014 to 2017 and were followed up at least one month. Our endpoint was 1 month-validated abstinence among the 1943 smokers followed up. We performed descriptive analyses of smokers, and predictors of abstinence were determined using a logistic regression model.

A 6.9% significant increase of first visits was observed during "Mois sans tabac" versus before Mois sans tabac (P<0.001). Furthermore, more women (56.3% vs. 52.2%) as well as more light smokers (28.7% vs. 23.7%) sought help between these two periods. Finally, in 2016-2017, more smokers consulted by personal initiative than were hospital-referred (45.8% vs. 36.3%) in comparison with 2014-2015. Nevertheless, there was no significant difference of cessation rate between the 2014-2015 group (44.6%) and the 2016-2017 group (45.6%). In multivariate logistic regression, being a light smoker was the only factor that increased the chances of abstinence in 2016-2017 compared to 2014-2015 (OR 1.68 [1.03-2.75]).

It seems important to refer smokers to cessation services during Mois sans tabac to reach high rates of abstinence.

It is important to establish if mechanical testing for physical problems in the human is specific or non-specific for structures - e.g. muscle and nerve. The median nerve at the wrist can be moved in preference to its adjacent flexor digitorum longus muscle, but it is necessary to know if this specificity extends to the elbow. We therefore measured mechanical behaviour of the median nerve at the elbow compared to its adjacent muscle - biceps brachii.

This cross-sectional study on nine fresh frozen cadaver upper limbs used differential variable reluctance transducers and Vernier callipers to measure strain and excursion in the median nerve and biceps brachii during cervical contralateral lateral flexion in glenohumeral abduction 0°, 30°, 60° and 90°.

Proximal excursion and strain with contralateral lateral flexion occurred in the median nerve primarily at 60° and 90° abduction (p<0.05), but no changes occurred in the muscle (p>0.05).

This study provides evidence of emphasising load to peripheral nerve over biceps at the elbow during cervical contralateral lateral flexion.

One main reason for these complications and costs is under-recognition of CI-AKI risk and under-treatment of patients with impaired renal status. 157 interventional cardiologists each cared for three simulated patients with common conditions requiring intravascular contrast media in three typical settings pre-procedurally, during the procedure, and post-procedure. We evaluated their ability to assess the risk of developing CI-AKI, make the diagnosis, and treat CI-AKI, including proper volume expansion and withholding nephrotoxic medications. Overall, the quality-of-care scores averaged 46.0% ± 10.5, varying between 18% to 78%. G007-LK solubility dmso The diagnostic scores for accurately assessing risk of CI-AKI were low at 57.1% ± 21.2% and the accuracy of diagnosis pre-existing chronic kidney disease was 50.2%. Poor diagnostic accuracy led to poor treatment proper volume expansion done in only 30.
