MamoRef: an optical mammography device using whole-field CW diffuse reflectance. Presentation, validation and preliminary clinical results.

MamoRef is an mammography device that uses near-infrared light, designed to provide clinically relevant information for the screening of diseases of the breast. Using low power continuous wave lasers and a high sensitivity CCD (Charge-coupled device) that captures a diffusely reflected image of the tissue, MamoRef results in a versatile diagnostic tool that aims to fulfill a complementary role in the diagnosis of breast cancer providing information about the relative hemoglobin concentrations as well as oxygen saturation.We present the design and development of an initial prototype of MamoRef.

Quality improvement collaborative to optimize heart failure care in patients from a network of clinics in Argentina during the COVID-19 pandemic.

Heart failure (HF) is a major clinical and public health problem associated with significant mortality, morbidity, and health-care costs. Despite the existence of evidence-based guidelines for the optimal treatment of HF, the quality of care remains suboptimal. Our aim was to increase the use a care bundle in 50% of enrolled subjects during their hospitalization and discharge and to reduce their readmission for HF causes by 10%.

Dynamic Relative Regional Lung Strain Estimated by Electrical Impedance Tomography in an Experimental Model of ARDS.

Background: To analyze the role of PEEP on dynamic relative regional strain (DRRS) in a model of ARDS, respective maps were generated by electrical impedance tomography (EIT).

Methods: Eight ARDS pigs submitted to PEEP steps of 0, 5, 10, and 15 cm HO at fixed ventilation were evaluated by EIT images. DRRS was calculated as (V/EELI)/(V/EELI), where the tidal volume (V) and end-expiratory lung impedance (EELI) are the tidal and end-expiratory change in lung impedance, respectively.
