This report describes adaptations madeto the provision of maternal and newborn care in the Uruguayan healthcare system during the early phase of the COVID-19 pandemic. It relies on data collected from 180 perinatal healthcare providers between March and July 2020 through a global online survey.&nbsp

The objective of this study was to compare integration of AlloDerm® acellular dermal grafts in animals subjected to non-ablative laser irradiation and animals not exposed to this therapy.Standardized AlloDerm® fragments measuring 5 mm² were grafted into the subcutaneous tissue overlying the calvaria in 32 Wistar rats. Laser therapy (685 ηm), at a dose of 4 J/cm2 per session, was applied immediately after surgical intervention and every 48 hours thereafter for a total of four applications.Analysis of histology slides revealed significantly greater edema in the control group. There was no neutrophil infiltration in the laser-irradiated group at any point during the study period, whereas such infiltration was present in control animals at three of the four points of observation. In the laser therapy group, lymphocyte infiltration was observed from day 1, whereas in the control group, it was only apparent from day 3. Vascularization was substantially greater in the control group. In the experimental group, the AlloDerm® graft was completely replaced by fibrous tissue.These findings suggest that add-on non-ablative laser therapy is an effective stimulator of healing and graft integration after placement of AlloDerm® acellular dermal grafts.

Six clinically healthy Arabian horses were submitted to a standard incremental exercise test, performed on a high-speed treadmill at a 6% slope, and initial speed of 1,8 m.s-1 for 5 minutes, then 4,0 m.s-1 for 3 minutes, 6,0 m.s-1 for 2 minutes and 8,0 m.s-1, 9,0 m.s-1, 10,0 m.s-1 and 11,0 m.s-1 for one minute for each of these speed. The end of the exercise test was defined as the point in which the horse was no longer able to keep pace with the treadmill. Gas exchange was measured through respiratory analyses horse mask on the last 10 seconds at the end of each speed transition and at 1, 2 and 3 minutes after the end of the exercise, defined as experiment moments. During exercise, it was noticed an increase on both VO2 and VCO2 with linear relationship between exercise and speed. Arabian horses VO2max was 114,9 mL.kg-1.min-1. The respiratory exchange ratio increased over 1,0 by the speed of 9,0 m.s-1, indicating the preponderance of the anaerobic metabolism, and remains at a high level on the post-exercise period.
