La Mara de Rafael Ramírez Heredia ou la dangereuse frontière des réalités et des représentations
Authors: Ducoux Antoine 
Published: November 2019

Centré sur l’activité criminelle du gang de la Mara Salvatrucha à la frontière du Mexique et du Guatemala, La Mara de Rafael Ramírez Heredia se distingue des représentations de la frontière articulant l’idée de transculturalité et d’hybridation. Quels savoirs sur la frontière et la criminalité de gang ce roman articule-t-il ? Cet article définit l’écriture de la frontière chez Ramirez Heredia comme une écriture des limites. Oscillant entre deux régimes de représentation contradictoires, cette écriture restitue une expérience sensible et complexe de la frontière, sans se déprendre d’une vision déterministe de la violence ni de stéréotypes mélodramatiques.

Published: November 2019

• Background Anxiety activates the sympathetic nervous system and hypothalamic-pituitary-adrenal axis and may increase morbidity and mortality in vulnerable critical care patients. Despite the adverse effects of anxiety, little is known about critical care nurses’ practices for assessing anxiety.• Objective To determine the importance that critical care nurses place on evaluating anxiety and to describe clinical indicators used to assess anxiety.• Methods Twenty-five hundred members of the American Association of Critical-Care Nurses received the Critical Care Nurse Anxiety Identification and Management Survey and were asked to rate the importance of anxiety assessment, to rate the importance of 61 anxiety indicators, and to select and rank the 5 most important anxiety indicators.• Results Seven hundred eighty-three completed surveys (31.6%) were returned by female (92.0%), white (88.6%) staff nurses (74.2%) who practiced critical care nursing 32.5 hours (SD, 12.3 hours) weekly. Nearly three quarters (71.3%) of respondents thought that anxiety assessment is very important. Only 2 indicators, agitation and patients’ verbalization of anxiety, were rated as very important to anxiety assessment. Thirty-nine indicators rated as important primarily included measurable physiological changes and observable behaviors. The top 5 anxiety indicators were agitation, increased blood pressure, increased heart rate, patients’ verbalization of anxiety, and restlessness.• Conclusion Important indicators of anxiety included observable behaviors and measurable physiological changes. Reliance on these criteria may produce an inaccurate and incomplete anxiety evaluation in vulnerable patients and lead to poorer outcomes. A comprehensive, systematic anxiety assessment tool for valid and reproducible evaluation of patients’ anxiety is needed.

Published: November 2019

• Background Although assessment for aspiration of small volumes of gastric contents in tube-fed patients receiving mechanical ventilation is important, available methods for this purpose are not wholly satisfactory. A potential method is immunoassay of tracheal secretions for the gastric enzyme pepsin.
• Objectives To determine the frequency with which pepsin in suctioned tracheal secretions from acutely ill, tube-fed patients receiving mechanical ventilation could be detected via an immunoassay.
• Methods A convenience sample of 136 specimens of suctioned tracheal secretions was collected from 30 acutely ill, tube-fed adults receiving mechanical ventilation. Multiple samples were obtained from 26 of the 30 patients (range, 2–11 per subject). An immunoassay with rooster polyclonal antibodies to purified human pepsin was used to detect pepsin in the secretions.
• Results Fourteen specimens tested positive for pepsin. Secretions from 5 patients accounted for the 14 pepsin-positive results. A significant relationship was found between the position of the head of the bed and the presence of pepsin in tracheal secretions (P&lt; .001). Of the 14 pepsin-positive specimens, 13 (92.9%) were obtained from subjects in a flat position.
• Conclusions A pepsin immunoassay can be used to detect pepsin in human tracheal secretions. If pepsin in tracheal secretions is considered an indicator of aspiration of gastric contents, aspiration occurred in 5 of the 30 subjects. A flat position is strongly associated with the presence of pepsin in tracheal secretions.

Published: November 2019

• Background Studies of resource utilization by patients with new-onset atrial fibrillation after coronary artery bypass grafting have addressed only length of stay and bed charges.• Objective To compare resource utilization between patients with new-onset atrial fibrillation and patients without atrial fibrillation after isolated coronary artery bypass grafting.• Methods Retrospective review of clinical and administrative electronic databases for 720 subjects who underwent isolated coronary artery bypass grafting with cardiopulmonary bypass in 25 months at one medical center. The prevalence of atrial fibrillation was determined, and resource utilization in various hospital cost centers was compared between subjects with and without atrial fibrillation.• Results The prevalence of new-onset atrial fibrillation was 33.1%. Compared with subjects without atrial fibrillation, subjects with atrial fibrillation had a longer stay (5.8 ± 2.4 vs 4.4 ± 1.2 days, P&lt; .001), more days receiving mechanical ventilation (P=.002) and oxygen therapy (P&lt; .001), and higher rates of readmission to the intensive care unit (4.6% vs 0.2%, P&lt; .001). Subjects with atrial fibrillation also had more laboratory tests (P&lt; .001) and more days receiving cardiac drugs, heparin, diuretics, and electrolytes. Subjects with atrial fibrillation had higher total postoperative charges ($57261 ± $17 101 vs $50 905 ± $10 062, P = .001), a mean difference of $6356. The mean differences were greatest for bed charges ($1642), laboratory charges ($1215), pharmacy ($989), and respiratory care ($582).• Conclusions The economic impact of atrial fibrillation after coronary artery bypass grafting has been underestimated.
Routine Daily Chest Radiography in Patients with Pulmonary Artery Catheters
Authors: Houghton Douglas , Cohn Stephen , Schell Vaunne , Cohn Kelly , Varon Albert 
Published: November 2019

• Background Pulmonary artery catheters are widely used invasive monitoring devices in critically ill patients. Clinicians disagree about whether daily chest radiographs are needed or clinical parameters alone are sufficient to verify catheter placement.• Objectives To determine whether daily chest radiographs are needed to assess migration of pulmonary artery catheters.• Methods One hundred consecutive patients with pulmonary artery catheters were prospectively evaluated. Clinical criteria for optimal position of the pulmonary artery catheters and findings on chest radiographs were compared. Optimal clinical criteria were (1) amount of air required to measure pulmonary capillary wedge pressure: 1.25 to 1.5 mL and (2) pulmonary artery catheter migrated 1 cm or less from initial position.• Results Three hundred ninety comparisons of clinical criteria and radiographic findings were done. Chest radiographs indicated the catheter required repositioning in 15 (4%) of 390 instances but in only 4 (1%) of 310 instances in which bedside clinical findings indicated adequate catheter position. In 69 (18%) of the 390 cases, the clinical criteria for adequate catheter position were not met, but radiographs showed the catheter in an appropriate position. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of abnormal clinical criteria were 73%, 82%, 81%, 14%, and 99%, respectively.• Conclusions Chest radiographs indicated that about 4% of catheters required repositioning. Catheter malposition can be reliably excluded (negative predictive value, 99%) by close observation of specific clinical criteria, so routine daily chest radiographs do not seem justified.
Association of Transient Myocardial Ischemia With Adverse In-Hospital Outcomes for Angina Patients Treated in a Telemetry Unit or a Coronary Care Unit
Authors: Pelter Michele M. , Adams Mary G. , Drew Barbara J. 
Published: November 2019

• Background Little is known about the frequency or consequences of transient myocardial ischemia in patients admitted to a telemetry unit for treatment of angina.
• Objectives To compare the rate of transient myocardial ischemia in a group of patients with angina treated in a telemetry unit with the rate in a similar group treated in a coronary care unit and to determine if transient myocardial ischemia is associated with adverse in-hospital outcomes.
• Methods Continuous 12-lead electrocardiography was used to monitor changes in the ST segment in 186 patients in the coronary care unit (1994–1996) and 186 patients in the telemetry unit (1997–2000). Transient myocardial ischemia was defined as a change from baseline of 100 μV or more in the ST segment in 1 or more leads lasting 60 seconds or longer.
• Results The rate of transient myocardial ischemia was 15% for patients in the telemetry unit and 19% for patients in the coronary care unit. Regardless of hospital unit, patients with transient myocardial ischemia were more likely than those without this complication to experience death or acute myocardial infarction after hospital admission. Most patients did not experience signs or symptoms during transient myocardial ischemia: 71% of patients in the telemetry unit versus 58% of patients in the coronary care unit (P = .28).
• Conclusions Transient myocardial ischemia is common among patients with angina treated in a telemetry unit. ST-segment monitoring may be useful for detecting patients with ischemia who may benefit from more aggressive therapies aimed at abolishing ongoing ischemia.

Authors: Holzinger Ulrike , Feldbacher Monika , Bachlechner Adelbert , Kitzberger Reinhard , Fuhrmann Valentin , Madl Christian 
Published: November 2019

Background Strict glycemic control in critically ill patients is challenging for both physicians and nurses.
Objectives To determine the effect of focused education of intensive care staff followed by implementation of a glucose control protocol.
Methods A prospective observational study in a medical intensive care unit in a university hospital. After intensive education of nurses and physicians, a glucose control protocol with a nurse-managed insulin therapy algorithm was developed and implemented. Every measured blood glucose value and insulin dose per hour and per day were documented in 36 patients before and 44 patients after implementation of the protocol.
Results Median blood glucose levels decreased after implementation of the protocol (133 vs 110 mg/dL; P &lt; .001). The amounts of time when patients’ blood glucose levels were less than 110 mg/dL and less than 150 mg/dL increased after implementation of the protocol (8% vs 44%; 75% vs 96%; P&lt;.001). The median use of insulin increased after implementation of the protocol (28 vs 35 IU/day; P=.002). Diabetic patients had higher median blood glucose levels than did nondiabetic patients both before (138 vs 131 mg/dL) and after (115 vs 108 mg/dL; P&lt;.001) implementation, although median insulin use also increased (before implementation, 33 vs 26 IU/day; P=.04; after implementation, 46 vs 30 IU/day; P &lt; .001).
Conclusions Use of a collaboratively developed glucose control protocol led to decreased median blood glucose levels and to longer periods of normoglycemia. Despite increased insulin use, glucose control was worse in diabetic patients.
