Transfusion Associated Dyspnea Profiling
Transfusion ReactionTransfusion reactions are defined as harms occurring during or after blood transfusion, with new heart/lung stress (eg. troubled breathing) regarded as cardiorespiratory transfusion reactions (CRTRs). CRTRs are among the most important, as the leading cause of transfusion-related harm and death. Though there are distinct classifications for these events, real life cases often don't fall neatly into a given category, with outliers regarded as "transfusion associated dyspnea (TAD)". It is unknown what TAD is -- whether it has a unique root cause, is a milder version of other known CRTRs, or is a blend of events. The purpose of this study is to better understand TAD and CRTRs by profiling them through a detailed medical history and more intensive laboratory assessment. This review of CRTRs may improve the quality/validity of final conclusions reported in the health record and to hemovigilance bodies, and uncover the nature of TAD and/or minimize CRTRs defaulting to the TAD category. Our enhanced understanding will advance diagnostic, treatment, and prevention efforts.
Auto-evaluation of Dyspnea
Lung DiseasesThe primary aim of this study was to compare patients-rated evaluation and caregiver's assessment of dyspnea with the standard tools in pulmonology unit (Borg scale and visual analog scale) and the secondary aim was to performed an analysis depending on the diseases (lung cancer vs. other lung diseases) and to verify the agreement between the evaluation between both visual analog scale and modified Borg scale.
The Reliability and Validity of Turkish Version of ''The Dyspnea-ALS-Scale (DALS-15)"
Amyotrophic Lateral SclerosisDyspneaThe Dyspnea-ALS-Scale (DALS-15) is a uni-dimensional scale to measure dyspnea in patients with Amyotrophic Lateral Sclerosis. It can be easily and rapidly applied. The aim of this study is to investigate reliability and validity of Turkish version of the DALS-15.
SELF - BREATHE for Chronic Breathlessness
COPDCancer3 moreSemi-structured qualitative interviews will be conducted to understand key factors that would enable / facilitate patients with chronic breathlessness to potentially use an online breathlessness intervention (SELF-BREATHE).
Bedside Lung Ultrasonography by Nurses in Acute Dyspnea.
Dyspnea; CardiacThis study assesses the potential of lung ultrasonography to diagnose heart failure.
Precision of IMED-4 Lung Fluid Measurements
DyspneaAcute Heart Failure Syndrome1 moreThe purpose of this study is to determine if IMED-4 recordings have sufficient precision to detect a clinically significant change in lung fluid status in acute heart failure syndrome with pulmonary congestion.
Database of All Patients Who Have Undergone Pulmonary Function Testing at Singapore General Hospital...
Obstructive Pulmonary DiseasesRestrictive Lung Disease2 moreThe purpose of this study is to create a prospective database of all patients who have undergone pulmonary function testing from which the investigators can study the clinical phenotypes of various respiratory conditions. The investigators hope by understanding the differences in these myriad phenotypes to be able to provide individualized, patient-targeted therapy in the future.
Lung Ultrasound for Acute Dyspnea in Emergency Department
DyspneaCongestive Heart FailureDyspnea is a frequent symptom in patients admitted to the Emergency Department (ED); discriminating between cardiogenic and non-cardiogenic dyspnea is a common clinical dilemma. The initial diagnostic work-out is often not very accurate in defining the etiology and the underlying pathophysiology. In the last years, lung ultrasound (US) has emerged as a useful real-time bedside diagnostic tool in the critical patient. The aim of this study was to evaluate the accuracy, reproducibility, and diagnostic impact of pleural and lung US, performed by emergency physicians at the time of patient first presentation to the ED, in identifying cardiac causes of acute dyspnea.
