SMALL AS WELL AS LARGE COLORECTAL LESIONS ARE EFFECTIVELY MANAGED BY ENDOSCOPIC MUCOSAL RESECTION TECHNIQUE.

Background: Endoscopic mucosal resection (EMR) is an easy-to-use treatment option for superficial colorectal lesions, including lesions ≥20 mm.

Objective: To evaluate the effectiveness of EMR.

Methods: We evaluated 430 lesions removed by EMR in 404 patients.

Membrane Distillation: Pre-Treatment Effects on Fouling Dynamics.

In the research reported in this paper, membrane distillation was employed to recover water from a concentrated saline petrochemical effluent. According to the results, the use of membrane distillation is technically feasible when pre-treatments are employed to mitigate fouling. A mathematical model was used to evaluate the fouling mechanism, showing that the deposition of particulate and precipitated material occurred in all tests; however, the fouling dynamic depends on the pre-treatment employed (filtration, or filtration associated with a pH adjustment).

Comparative effectiveness of 30 % trisodium citrate and heparin lock solution in preventing infection and dysfunction of hemodialysis catheters: a randomized controlled trial (CITRIM trial).

Background: Central venous catheters (CVC) are the only option when hemodialysis is needed for patients without definitive vascular access. However, CVC is associated with complications, such as infection, thrombosis, and dysfunction, leading to higher mortality and expenditures. The aim of this study was to compare the effectiveness of 30 % trisodium citrate (TSC30 %) with heparin as CVC lock solutions in preventing catheter-related bloodstream infections (CRBSI) and dysfunction in hemodialysis patients.

Prevalence of anxiety in patients admitted to a university hospital in southern Brazil and associated factors.

Objective: To identify the prevalence of anxiety in adults hospitalized in the clinical ward of a university hospital and to analyze the possible associated factors.

Method: A cross-sectional study was performed in a university hospital. All interviewees answered a specific questionnaire and the Hospital Anxiety and Depression Scale.
