RESUMO
BACKGROUND: Maternal psychological distress during pregnancy can negatively impact fetal development, resulting in long-lasting consequences for the offspring. These effects show a sex bias. The mechanisms whereby prenatal stress induces functional and/or structural changes in the placental-fetal unit remain poorly understood. Maternal circulating small extracellular vesicles (sEVs) are good candidates to act as "stress signals" in mother-to-fetus communication. Using a repetitive restraint-based rat model of prenatal stress, we examined circulating maternal sEVs under stress conditions and tested whether they could target placental-fetal tissues. RESULTS: Our mild chronic maternal stress during pregnancy paradigm induced anhedonic-like behavior in pregnant dams and led to intrauterine growth restriction (IUGR), particularly in male fetuses and placentas. The concentration and cargo of maternal circulating sEVs changed under stress conditions. Specifically, there was a significant reduction in neuron-enriched proteins and a significant increase in astrocyte-enriched proteins in blood-borne sEVs from stressed dams. To study the effect of repetitive restraint stress on the biodistribution of maternal circulating sEVs in the fetoplacental unit, sEVs from pregnant dams exposed to stress or control protocol were labeled with DiR fluorescent die and injected into pregnant females previously exposed to control or stress protocol. Remarkably, maternal circulating sEVs target placental/fetal tissues and, under stress conditions, fetal tissues are more receptive to sEVs. CONCLUSION: Our results suggest that maternal circulating sEVs can act as novel mediators/modulators of mother-to-fetus stress communication. Further studies are needed to identify placental/fetal cellular targets of maternal sEVs and characterize their contribution to stress-induced sex-specific placental and fetal changes.

Peripheral vascular injuries are uncommon in civilian trauma but can threaten the patient's life or the viability of the limb. The definitive control of the vascular injury represents a surgical challenge, especially if the patient is hemodynamically unstable. This article proposes the management of peripheral vascular trauma following damage control surgery principles. It is essential to rapidly identify vascular injury signs and perform temporary bleeding control maneuvers. The surgical approaches according to the anatomical injured region should be selected. We propose two novel approaches to access the axillary and popliteal zones. The priority should be to reestablish limb perfusion via primary repair or damage control techniques (vascular shunt or endovascular approach). Major vascular surgeries should be managed post-operatively in the intensive care unit, which will allow correction of physiological derangement and identification of those developing compartmental syndrome.

RESUMO
Abstract Noncompressible torso hemorrhage is one of the leading causes of preventable death worldwide. An efficient and appropriate evaluation of the trauma patient with ongoing hemorrhage is essential to avoid the development of the lethal diamond (hypothermia, coagulopathy, hypocalcemia, and acidosis). Currently, the initial management strategies include permissive hypotension, hemostatic resuscitation, and damage control surgery. However, recent advances in technology have opened the doors to a wide variety of endovascular techniques that achieve these goals with minimal morbidity and limited access. An example of such advances has been the introduction of the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), which has received great interest among trauma surgeons around the world due to its potential and versatility in areas such as trauma, gynecology & obstetrics and gastroenterology. This article aims to describe the experience earned in the use of REBOA in noncompressible torso hemorrhage patients. Our results show that REBOA can be used as a new component in the damage control resuscitation of the severely injured trauma patient. To this end, we propose two new deployment algorithms for hemodynamically unstable noncompressible torso hemorrhage patients: one for blunt and another for penetrating trauma. We acknowledge that REBOA has its limitations, which include a steep learning curve, its inherent cost and availability. Although to reach the best outcomes with this new technology, it must be used in the right way, by the right surgeon with the right training and to the right patient.
Resumen La hemorragia no compresible del torso es una de las principales causas de muerte prevenibles alrededor del mundo. Una evaluación eficiente y apropiada del paciente traumatizado con hemorragia activa es la esencia para evitar el desarrollo del rombo de la muerte (hipotermia, coagulopatía, hipocalcemia y acidosis). Actualmente, las estrategias de manejo inicial incluyen hipotensión permisiva, resucitación hemostática y cirugía de control de daños. Sin embargo, los recientes avances tecnológicos han abierto las puertas a una amplia variedad de técnicas endovasculares que logran esos objetivos con una morbilidad mínima y un acceso limitado. Un ejemplo de estos avances ha sido la introducción del balón de resucitación de oclusión aortica; REBOA ( Resuscitative Endovascular Balloon Occlusion of the Aorta , por sus sigla en inglés ), el cual, ha tenido gran provecho entre los cirujanos de trauma alrededor del mundo debido a su potencial y versatilidad en áreas como trauma, ginecología y obstetricia, y gastroenterología. El objetivo de este artículo es describir la experiencia lograda en el uso del REBOA en pacientes con hemorragia no compresible del torso. Nuestros resultados muestran que el REBOA puede usarse como un nuevo actor en la resucitación de control de daños del paciente con trauma severo, para este fin, nosotros proponemos dos nuevos algoritmos para el manejo de pacientes hemodinámicamente inestables: uno para trauma cerrado y otro para trauma penetrante. Se reconoce que el REBOA tiene sus limitaciones, las cuales incluye un periodo de aprendizaje, su costo inherente y la disponibilidad. A pesar de esto, para lograr los mejores resultados con esta nueva tecnología, el REBOA debe ser usado en el momento correcto, por el cirujano correcto con el entrenamiento y el paciente correcto.

PURPOSE: The objective of this study was to evaluate the implementation of a new single-pass whole-body computed tomography Protocol in the management of patients with severe trauma. METHODS: This was a descriptive evaluation of polytrauma patients who underwent whole-body computed tomography. Patients were divided into three groups: 1. Blunt trauma hemodynamically stable 2. Blunt trauma hemodynamically unstable and 3. Penetrating trauma. Demographics, whole-body computed tomography parameters and outcome variables were evaluated. RESULTS: Were included 263 patients. Median injury severity score was 22 (IQR: 16-22). Time between arrival to the emergency department and completing the whole-body computed tomography was under 30 minutes in most patients [Group 1: 28 minutes (IQR: 14-55), Group 2: 29 minutes (IQR: 16-57), and Group 3: 31 minutes (IQR: 13-50; p= 0.96)]. 172 patients (65.4%) underwent non-operative management. The calculated and the real survival rates did not vary among the groups either [Group 1: TRISS 86.4% vs. real survival rate 85% (p= 0.69); Group 2: TRISS 69% vs. real survival rate 74% (p= 0.25); Group 3: TRISS 93% vs. real survival rate 87% (p= 0.07)]. CONCLUSION: This new single-pass whole-body computed tomography protocol was safe, effective and efficient to decide whether the patient with severe trauma requires a surgical intervention independently of the mechanism of injury or the hemodynamic stability of the patient. Its use could also potentially reduce the rate of unnecessary surgical interventions of patients with severe trauma including those with penetrating trauma.
INTRODUCCIÓN: El objetivo de este estudio fue evaluar la implementación de un nuevo protocolo de tomografía computarizada corporal total para el manejo de pacientes con trauma severo. MÉTODOS: Este estudio es una evaluación descriptiva de pacientes que recibieron tomografía computarizada corporal total. Los pacientes fueron divididos en 3 grupos: 1. Trauma cerrado hemodinámicamente estables, 2. Trauma cerrado hemodinámicamente inestables y 3. Trauma penetrante. Se evaluaron las características demográficas, parámetros relacionados con la técnica y los desenlaces de los pacientes. RESULTADOS: Se incluyeron 263 pacientes. La mediana del puntaje de severidad de la lesión fue 22 (RIQ: 16-22). El tiempo entre el ingreso a urgencias y completar la tomografía corporal total fue menor a 30 minutos en la mayoría de pacientes [Grupo 1: 28 minutos (RIQ: 14-55), Grupo 2: 29 minutos (RIQ: 16-57), y Grupo 3: 31 minutos (RIQ: 13-50; p= 0.96). 172 pacientes (65.4%) recibieron manejo no operatorio. Las tasas de supervivencia calculadas y reales no difirieron entre ninguno de los grupos [Grupo 1: TRISS 86.4% vs. Tasa real de supervivencia 85% (p= 0.69); Grupo 2: TRISS 69% vs. Tasa real de supervivencia 74% (p= 0.25); Grupo 3: TRISS 93% vs. Tasa real de supervivencia 87% (p= 0.07)]. CONCLUSIÓN: Este nuevo protocolo de tomografía corporal total de un solo pase fue seguro, efectivo y eficiente para definir si los pacientes con trauma severo requieren o no una intervención quirúrgica. Su uso podría reducir la tasa de intervenciones quirúrgicas innecesarias en estos pacientes incluyendo los que se presentan con trauma penetrante.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging option for hemorrhage control, but its use is limited in scenarios such as penetrating chest trauma. The aim of this study was to describe the use of REBOA as a resuscitative adjunct in these cases with major hemorrhage and to propose a new clinical management algorithm. METHODS: This was a prospective, observational study conducted at a single Level I trauma center in Colombia. We included all patients older than 14 years with severe trauma who underwent REBOA from January 2015 to December 2019. Patients received REBOA if they were in hemorrhagic shock and were unresponsive to resuscitation. RESULTS: A total of 56 patients underwent REBOA placement of which 37 had penetrating trauma and 23 had chest trauma. All patients were hemodynamically unstable upon arrival to the emergency department, with a median systolic blood pressure of 69 mm Hg (interquartile range [IQR], 57-90 mm Hg) and median Injury Severity Score was 25 (IQR, 25-41). All REBOAs were deployed and inflated in zone 1, median inflation time was 40 minutes (IQR, 26-55 minutes), and no adverse neurologic outcomes were observed. Fifteen patients had REBOA and a median sternotomy. Eleven patients had concomitant abdominal wounds. Overall mortality was 28.6%, and there was no significant difference between penetrating versus blunt trauma patients (21.6% vs. 42.1%, p = 0.11). The survival rate of thoracic injured patients was similar to the predicted survival (65.2% vs. 63.3%). CONCLUSION: Resuscitative endovascular balloon occlusion of the aorta can be used safely in penetrating chest trauma, and the implementation of a REBOA management algorithm is feasible with a well-trained multidisciplinary team. LEVEL OF EVIDENCE: Therapeutic, level V.

Introducción. La tomografía corporal (TC) total en la evaluación de pacientes con trauma grave, puede ser una herramienta eficaz y segura para decidir entre un tratamiento quirúrgico y uno no quirúrgico, pero aún no son claras las implicaciones diagnósticas y los riesgos asociados con esta técnica.Métodos. Se incluyeron pacientes mayores de 15 años con trauma grave que fueron sometidos a TC total. Se evaluaron la seguridad, la efectividad y la eficiencia por medio de los parámetros de incidencia de nefropatía inducida por los medios de contraste, dosis total de radiación por paciente, proporción de casos en los que la TC total cambió el manejo, y el retraso en el diagnóstico. Resultados. Se incluyeron 263 pacientes, 83 % sufrieron trauma cerrado y 17 % sufrieron trauma penetrante. La gravedad de la lesión fue mayor en estos últimos y, sin embargo, el trauma cerrado con inestabilidad hemodinámica se presentó con mayores grados de choque. El 65 % de los pacientes recibió tratamiento selectivo no operatorio. Entre los subgrupos, no hubo diferencias significativas en el tiempo entre el ingreso a la sala de urgencias y la toma de la TC total (p=0,96) y, en la mayoría de los casos, el tiempo entre la práctica de la TC total y el diagnóstico de presencia o ausencia de heridas fue menor de 25 minutos. La mediana de radiación total estuvo por debajo de 20 mSv en todos los grupos. No hubo diferencias significativas en la mortalidad (p=0,17). Conclusión. La TC total es una herramienta segura y eficiente para decidir entre un tratamiento quirúrgico y uno no quirúrgico en los casos de trauma grave, independientemente del mecanismo de la lesión o la estabilidad hemodinámica al ingreso
Introduction: Total body tomography (CT) in the evaluation of patients with severe trauma may be an effective and safe tool to decide between a surgical or non-operative management, but the diagnostic implications and risks associated with this technique are still unclear.Methods: Patients older than 15 years with severe trauma who underwent total CT were included. Safety, effectiveness and efficiency were evaluated through the parameters of incidence of contrast-induced nephropathy, total radiation dose per patient, proportion of cases in which the total CT changed the management, and the delay in the diagnosis.Results: 263 patients were included, 83% presented with blunt trauma and 17% with penetrating trauma. The severity of the injury was higher in the latter, however, the blunt trauma with hemodynamic instability presented with higher degrees of shock. Non-operative management was selected in 65% of patients. Among the subgroups, there was no significant difference in the time between admission to the emergency room and taking the total CT (p=0.96), and in most cases, the time between the total CT and the diagnosis of presence or absence of injury was less than 25 minutes. The median total radiation was below than 20 mSv in all groups. There were no significant difference in mortality (p=0.170. Conclusion: Total CT is a safe and efficient tool to decide between a surgical and a non-operative management in patients with severe trauma, regardless of the mechanism of injury or hemodynamic stability at admission

OBJECTIVE: To explore the effects of digital facial image modification on children's body image and on parental support for children's healthy dietary and physical activity behaviors. STUDY DESIGN: Children and their parents were exposed to a novel image modification program that altered children's facial photographs to reflect weight loss and weight gain. The influences of facial image modification on children's body image and on parental support of children's healthy dietary and physical activity behaviors were measured with before and after surveys. RESULTS: Eighty-one children and their parents were surveyed. Forty percent of children were at risk for overweight or overweight, and 59% of parents surveyed were overweight or obese. Parents' support for children's healthy dietary and physical activity behaviors significantly increased after parents viewed altered facial images of their child. In contrast, no change in children's body image measures was demonstrated after children viewed weight-altered photographs of themselves. CONCLUSIONS: Facial image modification programs do not appear to have a detrimental effect on children's body image in the immediate post-exposure period. Image alteration may serve as an effective motivating tool to encourage parents to facilitate healthy dietary and physical activity behaviors in their children.

BACKGROUND: Endoscopic extraction of biliary tract stones is safe and effective. When the procedure is not successful, the use of a temporary stent can be a solution. AIM: To prospectively analyze the usefulness of endoscopic biliary stents in the temporary management of biliary obstruction due to choledocholithiasis. MATERIAL AND METHODS: Analysis of 51 consecutive patients (age range 21-88 years, 34 females) with common bile duct stones that, from January 1999 to December 2001, were subjected to an endoscopic insertion of a biliary stent. RESULTS: The indications for stent placement were a large stone in 40 patients (78%), the insecurity of a complete biliary tract cleaning in eight (16%) and technical difficulties in three (6%). Twenty seven patients (52.9%) were jaundiced and 17 (33.3%) had cholangitis. The prostheses remained in place until definitive resolution of the choledocholithiasis in 47 patients (92%) and migrated in 4 (8%). Bilirubin levels became normal in all cases with jaundice and infection resolved in all those with cholangitis. The definitive treatment of choledocholithiasis was done endoscopically in 28 patients (58%) and surgically in 20 (42%). Three patients were lost from follow up. Of these, one patient (2%) died 14 months later due to a recurrent cholangitis. The remaining two patients were asymptomatic and with the prostheses still in place 522 and 560 days post stent placement. CONCLUSIONS: When the immediate endoscopic resolution of choledocholithiasis is not possible, temporary stenting is a simple and safe therapeutic alternative that allows patients to be free of obstructive complications until the definitive treatment is carried out.
