[EX Q]: We report on the early and intermediate-term follow-up results of self-expanding Wallstent (Schneider, Switzerland) implanted in children with congenital heart disease.', 'The inherent shortcomings of balloon-expandable stents prompted the trial of an alternative stent.', 'Twenty patients underwent 22 implantations of 25 self-expanding Wallstents between December 1993 and June 1997 in two institutions. The mean age and weight were 10.8+/-4.5 years and 30.5+/-14.2 kg, respectively. The patients were divided into two groups: 1) Group I comprised 17 patients with pulmonary arterial stenoses, 2) Group II comprised four patients with venous stenoses (one belonged to both groups). Sixteen patients underwent recatheterization at a median of 5.8 months (range 0.5 to 31, mean 8.1 months) after stenting. Hemodynamic and angiographic changes after the interventional procedures and complications were documented.', 'All the stents were successfully deployed in the intended position. In Group I, the narrowest diameter of the stented vessel increased from 4.1+/-1.5 to 8+/-2 mm (95% increase, p < 0.0001) while the systolic pressure gradient across decreased from 24.6+/-15.8 to 12.1+/-11.4 mm Hg (51% decrease, p = 0.001). In Group II, the dimensional changes of the narrowest segment increased from 4.3+/-0.5 to 7.5+/-0.4 mm (75% increase, p = 0.003), and the pressure gradient reduced from 5.0+/-2.9 to 0.9+/-1.0 mm Hg (82% decrease, p = 0.04) across the stented venous channel. Distal migration of two optimally positioned stents occurred within 24 h of implantation. At recatheterization, significant neointimal ingrowth (>30% of the expanded diameter) was noted in 7 (28%) of the 25 implanted stents. This responded poorly to balloon dilation. Predisposing factors for the neointimal ingrowth included stents of smaller diameter (<9 mm) and longer period after implantation.

[EX Q]: The objective of the study was to evaluate work disability and its main associated factors in patients with early arthritis. Argentine Consortium for Early Arthritis (CONAART) is the first early arthritis cohort in Argentina. Patients with one or more swollen joints and less than 2 years of symptoms duration were followed up prospectively in 13 departments of rheumatology. Social, demographic, familiar, clinical, and laboratory data were recollected. At first year and every year, X-rays of hands and feet were performed and working status and pharmaco-economic data were recollected. Work status (employed, unemployed, retired) and type of work were assessed by direct interview using a predesigned questionnaire. Eight hundred forty-eight patients were included, rheumatoid arthritis (RA)\u2009=\u2009483 (57 %)and undifferentiated arthritis (UA)\u2009=\u2009365 (43 %), 694 (81.8 %) were women, median age was 46 years (interquartile range (IQR) 35-55.7) and median symptoms duration 7 months (IQR 3-12). Patients with RA had significantly higher disease activity, worse functional capacity and quality of life, and more severe radiological damage compared to UA patients. However work disability (unemployed patient) was comparable between groups (RA\u2009=\u200921 % versus UA\u2009=\u200918.6 % p\u2009=\u2009NS). In both groups, unemployed patients had higher disease activity score of 28 joints (DAS28), worse Health Assessment Questionnaire (HAQ) values, and less years of formal education (p value <0.005 in all comparisons). Radiological damage was greater in unemployed patients but this difference did not reach statistical significance. In multivariate analysis, disease activity was the main variable associated with unemployment in both groups. Joint involvement was the main cause of work disability in this cohort of patients with early arthritis, independently of the final diagnosis.

[EX Q]: Endoplasmic reticulum (ER) stress is induced in many forms of chronic liver disease and may promote the development of hepatocellular carcinoma. The activator protein 1 (AP-1) complex is a transcription factor that promotes hepatic carcinogenesis in response to cellular stress. The aim of this study was to determine the role of ER stress in the regulation of the hepatic AP-1 complex.', 'Human hepatocellular carcinoma (HepG2) cells and C57BL/6J mice were subjected to pharmacologic ER stress and the expression of AP-1-associated genes and proteins was assessed. To determine the role of MAPK signaling in ER stress-induced AP-1 activation, ER stress was induced in JNK- and ERK-inhibited HepG2 cells.', 'Induction of ER stress promoted the activation of both Jun- and Fos-related genes and proteins of the AP-1 complex in HepG2 cells and murine liver. Inhibition of ERK phosphorylation in HepG2 cells completely prevented ER stress-induced activation of the fos-related components of AP-1 whereas activation of Jun-related components was only partially attenuated. Conversely, inhibition of JNK phosphorylation in HepG2 cells reduced ER stress-induced activation of Jun-related components but did not prevent activation of fos-related components.
