    Competences on hypoglycemia management among healthcare professionals in a clinical hospital
    (SOC MEDICA SANTIAGO, 2011) Rojas, Luis; Achurra, Pablo; Pino, Felipe; Ramirez, Pedro; Lopetegui, Marcelo; Sanhueza A, Luis Manuel; Villarroel, Luis; Aizman, Andres
    Background: A tight glycemic control of hospitalized patients increases the risk of hypoglycemia, whose management is not always optimal. Aim: To assess the hypoglycemia management competences of a multidisciplinary team in a clinical hospital. Material and Methods: An anonymous questionnaire about hypoglycemia management was answered by 11 staff physicians, 42 residents and 28 nurses of the department of medicine and critical care unit of a university hospital. Results: Respondents had a mean of 60% of correct answers, without significant differences between groups. The capillary blood glucose level that defines hypoglycemia was known by most of the respondents, but the value that defines severe episodes was known only by 60%. The initial management and follow up was well known only for severe episodes. Less than 50% knew the blood glucose value that required continuing with treatment. Conclusions: Although most professionals are able to recognize hypoglycemia, the knowledge about is management if insufficient. (Rev Med Chile 2011; 139: 848-855).

    Implementation and design of customized ex vivo machine perfusion. Analysis of its first results
    (Wiley, 2021) Riveros, Sergio; Marino, Carlo; Ochoa, Gabriela; Morales, Emilio; Soto, Dagoberto; Alegria, Leyla; Josefina Zenteno, Maria; Branes, Alejandro; Achurra, Pablo; Rebolledo, Rolando A.
    The lack of organs available for transplantation is a global problem. The high mortality rates on the waiting list and the high number of discarded livers are reasons to develop new tools in the preservation and transplantation process. New tools should also be available for low-income countries. This article reports the development of customized normothermic machine perfusion (NMP). An ex vivo dual perfusion machine was designed, composed of a common reservoir organ box (CRO), a centrifugal pump (portal system, low pressure), and a roller pump (arterial system, high pressure). Porcine livers (n = 5) were perfused with an oxygenated normothermic (37celcius) strategy for 3 hours. Hemodynamic variables, metabolic parameters, and bile production during preservation were analyzed. Arterial and portal flow remain stable during perfusion. Total bilirubin production was 11.25 mL (4-14.5) at 180 minutes. The median pH value reached 7.32 (7.25-7.4) at 180 minutes. Lactate values decreased progressively to normalization at 120 minutes. This perfusion setup was stable and able to maintain the metabolic activity of a liver graft in a porcine animal model. Design and initial results from this customized NMP are promising for a future clinical application in low-income countries.

    Laparoscopic Roux-en-Y gastric bypass versus laparoscopic sleeve gastrectomy: a case-control study and 3 years of follow-up
    (ELSEVIER SCIENCE INC, 2012) Boza, Camilo; Gamboa, Cristian; Salinas, Jose; Achurra, Pablo; Vega, Andrea; Perez, Gustavo
    Background: Laparoscopic sleeve gastrectomy (LSG) has become a popular surgical procedure among bariatric surgeons. Few studies have compared the efficacy of the procedure to laparoscopic Roux-en-Y gastric bypass (LRYGB). We performed a case-control study to assess the surgical results, weight progression, and remission of co-morbid conditions.

    Transgastric repair of transfixing gastroesophageal junction gunshot wound: video case report
    (2021) Vela, Javier; Contreras, Caterina; Varas, Julián; Ottolino, Pablo; Ramos, Juan Pablo; Escalona, Gabriel; Díaz, Alfonso; Achurra, Pablo; Ceroni, Marco
    Abstract Managing traumatic injuries of the gastroesophageal junction (GEJ) is infrequent due to associated lesions of adjacent highly vascularized organs. Its anatomical localization in the upper abdomen makes the repair challenging to perform. A stable 23-year-old male was presented at the emergency department with two thorax gunshot wounds. Computed tomography revealed air in the periesophageal space and right hemopneumothorax with no injury of the major vessels. A chest tube was placed and the patient was transferred hemodynamically stable to the operating. Abdominal exploration identified injuries to the left diaphragm; liver lateral segment; 1-cm transfixing perforation of the GEJ and right diaphragmatic pillar. Primary repair of the GEJ was performed and patched with a partial fundoplication. The diaphragm was repaired and the liver bleeding controlled. Finally, drains and a feeding jejunostomy were placed. The patient had an uneventful early postoperative course and was discharged home on the 12th postoperative day.
