IMPACTO-MR: a Brazilian nationwide platform study to assess infections and multidrug resistance in intensive care units.

Objective: To describe the IMPACTO-MR, a Brazilian nationwide intensive care unit platform study focused on the impact of health care-associated infections due to multidrug-resistant bacteria.

Methods: We described the IMPACTO-MR platform, its development, criteria for intensive care unit selection, characterization of core data collection, objectives, and future research projects to be held within the platform.

Results: The core data were collected using the Epimed Monitor System® and consisted of demographic data, comorbidity data, functional status, clinical scores, admission diagnosis and secondary diagnoses, laboratory, clinical, and microbiological data, and organ support during intensive care unit stay, among others.

[Value of digital subtraction angiography in the imaging of a subcutaneously implanted, intra-arterial chemotherapy catheter].

Intraarterial chemotherapy is already a commonly accepted treatment method in isolated liver metastases. The high risk of transcutaneous injection of chemotherapeutic substances in the implanted catheter system requires a passage examination before the beginning of therapy. 32 digital subtraction angiograms for examination and documentation of the implanted catheter have been performed in 15 patients.

[Value of intra-arterial digital subtraction angiography].

Among 3000 digital subtraction angiographies which have been performed in our institute, 850 patients have been examined intraarterially. The advantage of i.a.
