Remote ischemic perconditioning was more effective reducing renal ischemia-reperfusion injury than administration of tramadol or association of both treatments.
Objective: to develop a model of training in video-surgery, of low cost and that uses a smartphone as an image-generating source. Methods: We developed a 38cm high, 40cm wide, 40cm long hexagonal-shaped training box, with a front opening of 12x8 cm for coupling the smartphone. The internal illumination is made with LED lamps and for the support of the smartphone, we used a selfie stick, fixed in the upper part of the box, that allows control of height, distance, angulation, and the coupling of devices with different formats. We selected 20 undergraduate students without previous training in video-surgery, who performed four exercises in the box, with assessment of the time and amount of errors in the execution of the tasks. Each student completed the training for three consecutive weeks. We collected the data in spreadsheets for later analysis. Results: Nineteen students completed the training program, with significant improvement in the times and in the number of errors. Conclusion: the developed model was feasible and promoted the acquisition of skills in this group of students. In addition, it presents low cost, is portable and uses common equipment, such as smartphones.

ARTIGO DESummary Purpose: To evaluate the hydrocortisone low-dose effects in hemorrhagic shock in rats. Methods: Twenty male Wistar rats were randomly distributed into 04 groups: Sham Group (GS); Shock group (CG), animals subjected to hemorrhagic shock; Group Hypertonic Saline 7.5% (GSH 7.5%), with volume replacement of saline solution at 7.5% after shock; Hydrocortisone Group (GH), animals received hydrocortisone after shock. Arterial blood gas samples and variations of the mean arterial blood pressure (MAP) were analyzed before the shock induction and after treatments. Intestinal samples were collected for histological analysis. Results: MAP was statistical significantly increased after treatment of the shock in GSH 7,5% (p=0.0001) and GH (p=0.0058) when compared to the CG. Regarding the arterial blood gas analysis, hydrocortisone increased pH of arterial blood in comparison to the GC (P=0.0372), lowered PaCO2 (p=0.0008), maintained higher levels of bicarbonate ions (p=0.0395) and lower levels of lactate (p=0.002). GH (p=0.02), as GSH7.5% (p=0.0147), showed less histological damage than the GC. Conclusion: Low dosages of hydrocortisone had protective effects against hemorrhagic shock in rats.
Objective To analyze the epidemiological profile of patients with vertebral trauma treated at a medical reference center at the state of Pará, Northern Brazil. Methods A quantitative and retrospective study conducted at Hospital Metropolitano de Urgência e Emergência (HMUE) in Ananindeua, Northern Brazil, from January 2020 to March 2020, using medical records of patients admitted to the hospital from January 2018 to December 2019. Results Data from 270 medical records from the orthopedic and trauma sector of the hospital were analyzed. Conclusion The predominant profile was male patients, aged between 20 and 29 years, with low social conditions, presenting compressive lesions of lumbar vertebrae, submitted to conservative intervention, with hospital stays of 8 to 30 days, and evolving to complete recovery without sequelae. Level of evidence II; Retrospective Study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
