RESUMO
BACKGROUND: Scientific research is fundamental to the education of medical students. However, their involvement in research is limited. AIM: To describe the perceptions of medical students about facilitators and constraints to perform undergraduate research. MATERIAL AND METHODS: Medical students attending the Chilean Congress of Medical Students in the Metropolitan Region in 2018, were surveyed. The responses obtained were subjected to a qualitative content analysis and were grouped according to perceptions of facilitators and constraints. RESULTS: The main facilitators reported were linkage with research teachers, personal motivation towards research, and research-oriented curriculum. The main constraints were lack of time for research, lack of access to formal information channels to engage in research, and sub-optimal conditions for research. CONCLUSIONS: The main factor promoting research at the undergraduate level was the link with the teacher, mainly through informal channels. The lack of official information provided through formal instances and lack of time hampers the access to research.

BACKGROUND: The participation of medical students in research generates professional, scientific, and personal benefits for the student. AIM: To evaluate the interest and opportunities for medical students in Chile to participate in scientific research and their perceptions about factors influencing research. MATERIAL AND METHODS: All students attending the 2018 Chilean Congress for Medical Students were invited to answer a 44 questions survey about interest and opportunities to participate in research. RESULTS: The survey was answered by 489 of the 538 students attending the congress. Eighty five percent referred interest in conducting scientific research, but only 47% had the opportunity to actively participate in a research project. The main research area providing opportunities was epidemiology and the main form to access a research project was through direct contact with a medical professor or researcher. Seventy seven percent of respondents had courses of scientific investigation in their medical curriculum and 92% had a scientific society for medical students in their university. CONCLUSIONS: Respondents showed a great deal of interest in participating in scientific research. However, there is a gap between this interest and the available opportunities. Medical professors should promote and facilitate the participation of their students in research.

BACKGROUND: Several studies have validated capillary refill time (CRT) as a marker of tissue hypoperfusion, and recent guidelines recommend CRT monitoring during septic shock resuscitation. Therefore, it is relevant to further explore its kinetics of response to short-term hemodynamic interventions with fluids or vasopressors. A couple of previous studies explored the impact of a fluid bolus on CRT, but little is known about the impact of norepinephrine on CRT when aiming at a higher mean arterial pressure (MAP) target in septic shock. We designed this observational study to further evaluate the effect of a fluid challenge (FC) and a vasopressor test (VPT) on CRT in septic shock patients with abnormal CRT after initial resuscitation. Our purpose was to determine the effects of a FC in fluid-responsive patients, and of a VPT aimed at a higher MAP target in chronically hypertensive fluid-unresponsive patients on the direction and magnitude of CRT response. METHODS: Thirty-four septic shock patients were included. Fluid responsiveness was assessed at baseline, and a FC (500 ml/30 mins) was administered in 9 fluid-responsive patients. A VPT was performed in 25 patients by increasing norepinephrine dose to reach a MAP to 80-85 mmHg for 30 min. Patients shared a multimodal perfusion and hemodynamic monitoring protocol with assessments at at least two time-points (baseline, and at the end of interventions). RESULTS: CRT decreased significantly with both tests (from 5 [3.5-7.6] to 4 [2.4-5.1] sec, p = 0.008 after the FC; and from 4.0 [3.3-5.6] to 3 [2.6 -5] sec, p = 0.03 after the VPT. A CRT-response was observed in 7/9 patients after the FC, and in 14/25 pts after the VPT, but CRT deteriorated in 4 patients on this latter group, all of them receiving a concomitant low-dose vasopressin. CONCLUSIONS: Our findings support that fluid boluses may improve CRT or produce neutral effects in fluid-responsive septic shock patients with persistent hypoperfusion. Conversely, raising NE doses to target a higher MAP in previously hypertensive patients elicits a more heterogeneous response, improving CRT in the majority, but deteriorating skin perfusion in some patients, a fact that deserves further research.
