Safety of magnetic resonance imaging one to three days after bare metal and drug-eluting stent implantation

Despite emerging evidence that magnetic resonance imaging (MRI) is safe within 8 weeks after bare metal coronary stenting, there are limited data on the safety of MRI imaging very early (1 to 3 days) after stent implantation and no published studies to date on the safety of MRI after insertion of drug-eluting stents (DESs). Forty-nine patients underwent cardiovascular MRI (1.5 T) at a median of 1 day after complex percutaneous coronary intervention. The average number of stents per patient was 2.2 +/- 1.1, and the average stent length per patient was 37.8 +/- 19.7 mm. In 15 of these patients > or =1 DES was used: paclitaxel DESs in 14 and sirolimus DESs in 1. In the DES group, the average number of stents was 1.75 +/- 1.0 per patient (3 patients received 3 DESs), and average DES length was 36.5 +/- 14.8 mm per patient. No acute thrombosis was recorded, and at 9-month clinical follow-up only 2 patients (4%) developed adverse events (1 target vessel restenosis and 1 nontarget vessel revascularization); these patients were in the non-DES group.     

Influence of patient personality in the treatment of rheumatoid arthritis

Individualized treatment of rheumatoid arthritis (RA) based on genetic/serologic factors is increasingly accepted. Moreover, patients are more actively involved in the management of their disease. However, personality has received little attention with respect to perception of the need and adherence to treatment. Our objective was to evaluate whether patient personality was associated with the acceptance or rejection of more aggressive early treatment. We performed a cross-sectional study in two hospitals with early arthritis clinics where sociodemographic, clinical, and therapeutic variables are systematically recorded. Patients completed Eysenck Personality Questionnaire, Multidimensional Health Locus of Control, Pain-Related Self-Statement Scale and Pain-Related Control Scale. Aggressive treatment was considered if patients received more than two DMARDs or biological agents during the first year of follow-up. Multivariate logistic regression analysis was performed to determine predictors of aggressive treatment. One hundred seventy-six RA patients were included (80 % women, disease begin median age 55 years). Treatment was considered aggressive in 57.9 % of the sample. Scores were high in extraversion in 50.8 % of patients, neuroticism in 29.5 % and psychoticism in 14.7 %. Neuroticism was the only factor associated with aggressive treatment, which was less probable (p = 0.04, OR = 0.40). Neuroticism also decreased the possibility of receiving a combination of biologics and DMARDs (p = 0.04, OR = 0.28). Patients with high scores on neuroticism are more worried, obsessive and hypochondriac, leading them to reject more aggressive therapy. It is important to educate about their disease so that they will accept more aggressive approaches in clear cases of poor outcome.     

Documento de posicionamiento de la AEG,la SEED y la SEAP sobre calidad de la endoscopia digestiva alta para la detección y vigilancia de las lesiones precursoras de cáncer gástrico

This position paper, sponsored by the Asociación Española de Gastroenterología [Spanish Association of Gastroenterology], the Sociedad Española de Endoscopia Digestiva [Spanish Gastrointestinal Endoscopy Society] and the Sociedad Española de Anatomía Patológica [Spanish Anatomical Pathology Society], aims to establish recommendations for performing an high quality upper gastrointestinal endoscopy for the screening of gastric cancer precursor lesions (GCPL) in low-incidence populations, such as the Spanish population. To establish the quality of the evidence and the levels of recommendation, we used the methodology based on the GRADE system (Grading of Recommendations Assessment, Development and Evaluation). We obtained a consensus among experts using a Delphi method. The document evaluates different measures to improve the quality of upper gastrointestinal endoscopy in this setting and makes recommendations on how to evaluate and treat the identified lesions. We recommend that upper gastrointestinal endoscopy for surveillance of GCPL should be performed by endoscopists with adequate training, administering oral premedication and use of sedation. To improve the identification of GCPL, we recommend the use of high definition endoscopes and conventional or digital chromoendoscopy and, for biopsies, NBI should be used to target the most suspicious areas of intestinal metaplasia. Regarding the evaluation of visible lesions, the risk of submucosal invasion should be evaluated with magnifying endoscopes and endoscopic ultrasound should be reserved for those with suspected deep invasion. In lesions amenable to endoscopic resection, submucosal endoscopic dissection is considered the technique of choice.     

Epidemiological and clinical interaction between HTLV-1 and Strongyloides stercoralis

Strongyloides stercoralis is the most common human parasitic nematode that is able to complete a life cycle and proliferate within its host. The majority of patients with strongyloidiasis have an asymptomatic infection or mild disease. However, when autoinfection occurs, a high number of infecting larvae can gain access to the bloodstream by penetrating the colonic mucosa leading to a severe hyperinfection and the development of disseminated strongyloidiasis. The human T cell lymphotropic virus type 1 (HTLV-1) predominantly infects T cells and induces spontaneous lymphocyte proliferation and secretion of high levels of type 1 cytokines. Strongyloides stercoralis patients with HTLV-1 co-infection have a modified immunological responses against parasite antigens and co-infection has clinical implications for strongyloidiasis. The high production of IFN-gamma observed in patients co-infected with HTLV-1 and Strongyloides stercoralis decreases the production of IL-4, IL-5, IL-13 and IgE, molecules that participate in the host defence mechanism against helminths. Moreover, there is a decrease in the efficacy of treatment of Strongyloides stercoralis in patients co-infected with HTLV-1. Alterations in the immune response against Strongyloides stercoralis and the decrease in the efficacy of anti-parasitic drugs are responsible for the increased prevalence of Strongyloides stercoralis among HTLV-1 infected subjects and make HTLV-1 infection the most important risk factor for disseminated strongyloidiasis.     

The changing role of residential intervention

ABSTRACT

The role of therapeutic residential care (TRC) is changing. In fact, this article reframes the terminology of TRC and uses “residential interventions” to more accurately reflect that residential programs provide time-limited “intervention” and treatment efforts must connect and extend to families and communities. Such changes are being compelled by necessity and innovation. Necessity is demanding evidence, data, and durable positive outcomes for this expensive intervention. Innovation is transforming basic service delivery through meaningful inclusion of youth and families and effective collaboration with community-based organizations. Service elements that confound this changing role are being reconsidered, including reductions in length of stay, a focus on long-term permanency, and the location of the actual intervention from program-centric practice to interventions in the home and community.

Endothelins and markers of renal damage in recently diagnosed hypertensive patients

Endothelin has been identified as a potent vasoconstrictor. The aim of this study was to evaluate urinary endothelins and their relation to other markers of renal damage, such as microalbuminuria, creatinine, and N-acetyl-beta-glucosaminidase (NAG), in a group of recently diagnosed (less than 1 year) hypertensive subjects and a control group. We selected 50 subjects and divided them into two groups: 27 hypertensive patients (15 females and 12 males) without previous pharmacologic therapy, and 23 healthy, normotensive subjects (12 females and 11 males). All patients underwent a history and physical examination, chest x-ray, electrocardiography, funduscopy, and hematologic and biochemical analyses. Endothelins, microalbuminuria, creatinine, and NAG values were also determined in 24-hour urine samples. Creatinine, microalbuminuria, and NAG values were found to be higher in hypertensive than in normotensive subjects. The hypertensive group showed a nonsignificant elevation of total endothelin. In conclusion, the determination of elevated urinary endothelin does not appear to be an early marker of organ damage in hypertensive subjects. The urinary excretion of protein, creatinine, and NAG was higher in hypertensive subjects. A positive correlation was found between the urinary excretion of endothelins and markers of renal damage, microalbuminuria and NAG values. The relationship between endothelins and hypertension was without statistical significance.
