Chagas disease cardiomyopathy(CCC), the main consequence of Trypanosoma cruzi(***) infection, is an inflammatory cardiomyopathy that develops in up to 30% of infected individuals. The heart inflammation in CCC patients is characterized by a Th1 T cell-rich myocarditis with increased production of interferon(IFN)-γ, produced by the CCC myocardial infiltrate and detected at high levels in the periphery. IFN-γ has a central role in the cardiomyocyte signaling during both acute and chronic phases of *** infection. In this review, we have chosen to focus in its pleiotropic mode of action during CCC, which may ultimately be the strongest driver towards pathological remodeling and heart failure. We describe here the antiparasitic protective and pathogenic dual role of IFN-γ in Chagas disease.

AIM To evaluate the incidence of anastomotic strictures after intestinal resection in Crohn's disease(CD), demonstrate long-term efficacy and safety of endoscopic balloon dilation(EBD) in CD strictures and its impact on the diagnosis of subclinical postoperative endoscopic recurrence. METHODS Retrospective single tertiary center study based on prospectively collected data between 2010 and 2015including anastomotic and non-anastomotic strictures. RESULTS29% of 162 CD patients included developed an anastomotic stricture. 43 patients with anastomotic strictures and 37 with non-anastomotic strictures underwent EBD; technical success was 97.7% and 100%, respectively, however, 63% and 41% needed repeat dilation during the 4.4-year follow-up. Longer periods between surgery and index colonoscopy and higher lactoferrin levels were associated with the presence of stricture after surgery. Calprotectin levels > 83.35 μg/g and current or past history of smoking were associated with a shorter time until need for dilation(HR = 3.877, 95%CI: 1.480-10.152 and HR = 3.041, 95%CI: 1.213-7.627). Anastomotic strictures had a greater need for repeat dilation(63% vs 41%, P = 0.047). No differences were found between asymptomatic and symptomatic cohorts. Disease recurrence diagnosis was only possible after EBD in a third of patients. CONCLUSION EBD is an effective and safe alternative to surgery, with a good short and long-term outcome, postponing or even avoiding further surgery. EBD may allow to diagnose disease recurrence in patients with no clinical signs/biomarkers of disease activity.

A hundred Pseudomonas aeruginosa strains from several clinical specimens from five hospitals in Sao Luís-MA were evaluated for biofilm production, prevalence of the gene algD, adhesion to HEp-2 cells and antimicrobial susceptibility. The most affected clinical specimens and hospital sectors were also evaluated. Most isolates were obtained from the tracheal aspirate (21.0%) and the most affected hospital sector was the ICU (43.0%). The antibiotics with the highest sensitivity rate were amikacin, piperacillin/tazobactam, fluoroquinolones, gentamicin and meropenem and the ones with the highest resistance rate were aztreonam, ceftazidime and cefepime. All samples were sensitive to polymyxin B. In relation to the expression of the gene for ESBL, 50.0% (17/34) of the multiresistant strains showed the enzyme TEM. Most strains showed high hydrophobicity and 96% of the isolates produced biofilm on a polystyrene microplate, 52% were capsule producers, 19% showed mannose-sensitive fimbriae and 39% expressed the gene algD. We observed adhesion to HEp-2 cells and to the coverslip. These factors may be reported in the pathogenesis of this bacterium, what represents a potential risk for colonization of medical devices which favor the establishment of chronic nosocomial infections.

This study aimed to analyze the concept of nursing care to patients with breast cancer on chemotherapy treatment, according to the perspective of the person submitted to care. The study followed the conceptual analysis methodology proposed by Walker and Avant according to Waldow, and it was developed through consultation to SCOPUS and CINAHL databases. The selection was carried out by inclusion and exclusion criteria, constituting a sample of 7 articles. There have been identified the main uses of the risk concept, defining attributes, antecedents and consequences of the concept. The evaluation of the concept and nursing care to breast cancer patient on chemotherapy treatment allowed a broader understanding of the phenomenon, with emphasis on the skills and competencies in nursing care dispensed to woman on chemotherapy treatment for breast cancer.
