Stress level assessment among health care workers involved in the management of critically ill COVID-19 patients.

BACKGROUND: Intensive care health care workers (HCWs) are frontlines of this crisis as they deal with critically ill COVID-19 patients which can potentially affect their mental well-being and causes different levels of stress. AIM: To determine the prevalence of stress among HCWs involved in the management of critically ill COVID-19 patient, identify the factors associated with stress, and highlight the availability of psychological support provided to HCWs. METHODS: A cross-sectional multicenter, international study using a web-based questionnaire of 27 questions including the Perceived Stress Scale-10 (PSS-10) for assessment of stress level. Questions to identify factors associated with stress, the psychological support provided, and the sociodemographic characteristics were included. RESULTS: We received a total 1649 responses from 59 countries: 550 (34%) were from Europe, 525 (32.36%) from Asia, 283 (17.44%) from Africa, 177 (11%) from America, and 88 (5.42%) from Australia. The average stress level was 22 points on the PSS denoting moderate stress in 1327 (81.8%) respondents, while 239 (14.73%) respondents had a severe level of stress. Female gender, working in high capacity units and remote areas in addition to lack of psychological support, was significantly associated with stress in our study. CONCLUSION: Stress level was moderate to severe among intensive care HCWs during this pandemic, and many factors were associated with stress emphasizing the importance of psychological support during that unprecedented pandemic.

COVID-19-related Posterior Reversible Encephalopathy Syndrome in an Adult ICU Patient in Ireland.

Radiologically confirmed, novel coronavirus disease 2019 (COVID-19)-related neurological manifestations are being reported with increasing frequency since the outbreak of the disease. We describe a 54-year-old male with COVID-19, who demonstrated radiological and clinical findings of posterior reversible encephalopathy syndrome(PRES). The proposed mechanism suggested for COVID-19-related PRES is a disease induced inflammatory storm, which causes endothelial injury, resulting in endothelialdysfunction (ED), interstitial fluid extravasation and cerebral edema. Key Words: COVID-19, Encephalopathy, Neurological complications, PRES.

Coagulopathy after cardiac surgery may be influenced by a functional plasminogen activator inhibitor polymorphism.

BACKGROUND: Cytokine-mediated inflammation and coagulopathy may occur after cardiac surgery. In this study we investigated the temporal pattern of plasminogen activator inhibitor-1 (PAI-1) gene expression after cardiac surgery and its relation with PAI genotype, and obtained preliminary data regarding its relation to perioperative morbidity. METHODS: The relative change in PAI-1 mRNA 1, 6, and 24 h after cardiopulmonary bypass (CPB) was measured from mononuclear cells in 82 patients undergoing elective cardiac surgery. DNA was analyzed for carriage of the 4G/5G PAI-1 polymorphism. RESULTS: PAI-1 gene expression decreased after CPB in all patients. A larger reduction in PAI-1 gene expression was observed in homozygous carriers of the 5G allele. Homozygous carriers of the 5G allele were also more likely to receive transfusion of coagulation blood products. There was no relation between change in PAI-1 gene expression and duration of CPB. CONCLUSIONS: PAI-1 gene expression decreased over time after CPB. We found a link between PAI-1 genotype, PAI gene expression, and transfusion of coagulation products after cardiac surgery.

Postoperative behavioral changes following anesthesia with sevoflurane.

BACKGROUND: Behavioral disturbance following hospitalization is a relatively frequent event, some children still having negative behavioral changes (NBC) 1 month following their operation. Sevoflurane has a propensity to induce 'excitement' during induction of anaesthesia, and delirium in the immediate postoperative phase. The aim of this study was to evaluate whether this translates into prolonged behavioral change. METHODS: A total of 120 children presenting for daycase surgical procedures under anesthesia were included in the study. Children were randomized to induction and maintenance of anesthesia with sevoflurane or halothane. No additional sedative drugs were administered. Postoperative behavioral change was assessed using the Post-Hospital Behavior Questionnaire (PHBQ) on postoperative days 1, 7 and 30. RESULTS: The Sevoflurane group (n = 63) were more distressed on emergence of anesthesia than the Halothane group (n = 57) (P < 0.05). About 58.3, 46.8 and 38.3% of all children exhibited NBC on postoperative days 1, 7 and 30, respectively. There was no association between anesthetic agent and behavior. There was a significant relationship between decreasing age and NBC (P < 0.005). CONCLUSIONS: Children anesthetized with sevoflurane exhibit more immediate postoperative distress than those anesthetized with halothane. This difference is not carried over into the longer posthospital period. Negative behavioral changes occur more frequently with decreasing age.

Comparison between repeat bolus intrathecal morphine and an epidurally delivered bupivacaine and fentanyl combination in the management of post-thoracotomy pain with or without cyclooxygenase inhibition.

OBJECTIVE: To compare the analgesic efficacy of a traditional epidurally delivered bupivacaine/fentanyl combination with a repeat bolus intrathecal morphine technique in the management of post-thoracotomy pain and to assess further the effect of cyclooxygenase (COX) inhibition on both modalities. DESIGN: Prospective, randomized, blinded study. SETTING: University teaching hospital. PARTICIPANTS: Patients having thoracic surgery. INTERVENTIONS: Epidural and intrathecal catheters were inserted. Blood and urine samples were collected for analysis. COX-1 and COX-2 inhibition with ibuprofen and nimesulide (COX-2 selective) was instituted. MEASUREMENTS AND MAIN RESULTS: Pain was assessed at rest and coughing by visual analog scale. Peak expiratory flow rate, patient satisfaction rating, sedation score, analgesic requirements, and preoperative and postoperative urinary creatinine levels were measured. The spinal and nimesulide combination showed the lowest pain scores (p < 0.001), least reduction in peak expiratory flow rate (p < 0.001), and highest patient satisfaction rating (p = 0.02). COX inhibition did not affect analgesic requirements in the epidural group or increase urinary creatinine in any group. CONCLUSION: The intrathecal morphine and nimesulide combination offered significantly better analgesia than any other combination studied. The efficacious interaction between opioids and nonsteroidal anti-inflammatory drugs may be COX-2 mediated.
