The Effect of High Frequency Oscillation on Biological Markers of Lung Injury

Acute Respiratory Distress Syndrome

Although mechanical ventilation is life saving, it is associated with a number of severe complications collectively referred to as ventilator induced lung injury (VILI). VILI contributes to the high morbidity and mortality associated with the acute respiratory distress syndrome (ARDS). Within the context of a randomized study evaluating the feasibility of conducting a study comparing high frequency oscillation to conventional lung protective ventilation in early severe ARDS, we are evaluating the effect of both ventilator strategies on biological markers of VILI.

Knowledge, Attitude and Practice of Dental Students About COVID-19

Acute Respiratory Distress SyndromeCorona Virus Infection7 more

Coronavirus disease 2019 (abbreviated "COVID- 19") is a pandemic respiratory disease that is caused by a novel coronavirus and was first detected in December 2019 in Wuhan, China. The disease is highly infectious, and its main clinical symptoms include fever, dry cough, fatigue, myalgia, and dyspnoea.1 In China, 18.5% of the patients with COVID-19 developed to the severe stage, which is characterized by acute respiratory distress syndrome, septic shock, difficult-to-tackle metabolic acidosis, and bleeding and coagulation dysfunction. After China, COVID-19 spread across the world and many governments implemented unprecedented measures like suspension of public transportation, the closing of public spaces, close management of communities, and isolation and care for infected people and suspected cases. The Malaysian government had enforced Movement Control Order (MCO) from 18th March to 4th May 2020 and henceforth Conditional Movement Control Order (CMCO) until 9th June 2020. The battle against COVID-19 is still continuing in Malaysia and all over the world. Due to the CMO and CMCO in the country, public and private universities have activated the e-learning mode for classes and as the government ordered, universities are closed and no face-to-face activities allowed. This has forced students of all disciplines including dentistry to stay at home which are wide-spread across Malaysia and shift to e- learning mode. To guarantee the final success for fight against COVID-19, regardless of their education status, students' adherence to these control measures are essential, which is largely affected by their knowledge, attitudes, and practices (KAP) towards COVID-19 in accordance with KAP theory. Once the restrictions are eased students have to come back and resume their clinical work in the campus. Hence, in this study we assessed the Knowledge, Attitude, and Practice (KAP) towards COVID-19 and the students preference for online learning.

The Effect of Using High-flow Nasal Oxygen-delivery System in Patients Under Intravenous General...

Pulmonary AtelectasesLung Injury1 more

In general anesthesia, gas exchange was altered by shunt and uneven ventilation perfusion ratios. Lung atelectasis was a cause of impaired oxygenation. High-flow nasal cannula oxygen therapy delivers adequately heated and humidified medical gas at up to 60 L/min of flow. It has physiological effects: reduction of anatomical dead space, positive end expiratory pressure (PEEP) effect, constant fraction of inspired oxygen, and good humidification. The hypothesis of this study is using high-flow nasal oxygen in intravenous general anesthesia could improve lung function and prevent lung atelectasis.

Remote Ischemic Preconditioning on Pulmonary Injury in Cardic Surgery

Lung InjuryRemote Ischemic Preconditioning

During cardiac surgery with cardiopulmonary bypass , pulmonary dysfunction remains to be a problem complicating the postoperative course of the patients.Remote ischemic preconditioning(RIPC) with transient upper limb ischemia/reperfusion is a novel, simple, cost-free,non-pharmacological and non-invasive strategy.Recent several trials suggested that RIPC could provide pulmonary protection by reducing serum biomarkers,however,whether the RIPC can improve the clinical outcomes in patients undergoing on-pump cardiac surgery,is still uncertain. The study hypothesis is: remote ischemic preconditioning will provide lung-protective effect and improve clinical outcomes in patients undergoing cardic surgery.

A Open Label, Post Marketing Surveillance Study Following Transfusion of INTERCEPT Platelet Components...

Transfusion Related Acute Lung Injury

This study is a prospective, non-randomized sequential cohort, open label, multi-center, non-inferiority, Phase IV surveillance study following transfusion of INTERCEPT PCs. The patient population will be hematology-oncology patients, including those undergoing hematopoietic stem cell transplant (HSCT), expected to require one or more PC transfusions. For each participating center, the study will start with a brief pilot run-in period with a group of at least 5 patients exposed only to conventional PCs. The purpose of this pilot run-in is to evaluate study logistics and data collection methods within each study center. Data from the pilot phase will be included in the data analysis for the treatment comparison. After the pilot run-in period, the study will be conducted in two sequential patient cohorts: 1) the Control cohort during which study patients will receive only conventional PCs, and 2) the INTERCEPT cohort during which patients will receive only INTERCEPT PCs. Patient enrollment at each Center will be monitored to target similar numbers of patients into the Control and Test Cohorts within each center. Centers may enroll Control and Test patients in ratios that vary from 2:1 to 1:2 due to institutional requirements to move rapidly to full INTERCEPT implementation, or due to availability issues with either Test or Control components. Within each Center, patient enrollment will be stratified in four categories: (1) chemotherapy only; and by use of conditioning regimens for hematopoietic stem cell transplantation (HSCT) in (2) myeloablative conditioning, (3) non-myeloablative conditioning, and (4) reduced intensity using the Center for International Blood and Marrow Transplant Research (CIBMTR) criteria. Note time from last chemotherapy treatment to first study transfusion should be no more than 30 days. To ensure both Test and Control cohorts have a similar allocation ratio (±10% per category) among the conditioning regimen strata, enrollment caps will be set for the Test cohorts, hence no Test patients will be enrolled to a stratum once the cap for the given stratum is met. Eligible patients will be enrolled in open Test strata sequentially as long as there is sufficient Test PC inventory available. Enrollment may be delayed for the Test cohort if sufficient inventory of Test PCs is not available.

Transpulmonary Pressure Gradients in High Frequency Oscillation

Acute Lung Injury

Patients with severe lung conditions occasionally require support with a special ventilator (breathing machine) called the High Frequency Oscillator (HFO). Effective ventilation requires that the pressure generated by the ventilator be as high as possible but not too high as this can damage the lungs. In patients on HFO, there is not a well defined way to measure this pressure. We will insert a small probe into the esophagus of patients on HFO to see if this is an accurate way to measure lung pressures for these patients. A better understanding of these pressures could lead to improved patient care.

Transfusion-related Acute Lung Injury: a Prospective Cohort Study in Critically Ill Children

Acute Lung Injury

Transfusions cause more adverse events in children than in adults. Patients in pediatric intensive care units (PICU) are particularly exposed to transfusions of plasma-rich blood products (red blood cell (RBC), plasma and platelets) and the risk of adverse events after a transfusion is particularly high in this vulnerable population. Transfusion-related acute lung injury (TRALI), an acute inflammation of the lungs that impairs gas exchange leading to acute respiratory failure, is one of the 2 most deadly transfusion complications in the general population. There is limited evidence on TRALI incidence and impact in critically ill children. This reduces the awareness of PICU team for this complication, and makes the decision process to transfuse particularly difficult. Moreover, acute lung injury is highly prevalent in critically ill children. It is therefore complex to ascertain if the high frequency of respiratory deteriorations observed after a transfusion in PICU is explained by the transfusion itself or by the evolution of the patient's critical illness. The investigators will conduct a cohort study of consecutive transfused critically ill children, with a control group of matched non-transfused children. The primary objective is to determine if transfusion of RBC, plasma and/or platelets in PICU is an independent risk factor of TRALI, and to compare the respiratory evolution in the two matched (transfused and non-transfused) groups. The secondary objectives will include the determination of the incidence rate, risk factors and clinical impact of TRALI in transfused PICU patients. The investigators will study both "classic TRALI" and "delayed TRALI".
