A systematic review of the symptomatic treatment of the cough in whooping cough
… are between 20 - 40 million cases of whooping cough annually world-wide, 90% of which occur in developing countries, resulting in an estimated 200 - 300 O00 fatalities each year. Much of the morbidity is due to the paroxysmal cough. Corticosteroids, salbutamol (a β₂- adrenergic stimulant), and …

Cough endpoint detection in continuous audio recordings
Cough detection and monitoring plays an important role in the assessment of respiratory conditions in patients. Cough audio can also prove valuable information for models used in the classification and diagnosis of diseases. However, cough detection remains a challenging problem due to variables in …

The role of cough in severe asthma
Rationale: <br/>Cough is a common symptom within asthma that is both important and troublesome for patients and has been shown to be associated with a less well controlled disease. However, the role of cough within asthma is not well understood and there is little knowledge as to how cough is …

Mycobacterium tuberculosis Lipids Activate Neurons and Trigger Cough
… tuberculosis (Mtb), manifests with a persistent cough as both a primary symptom and a transmission mechanism. While nociceptive neurons innervating the lungs trigger the cough reflex and some bacteria produce neuron-targeting molecules, how pulmonary Mtb infection causes cough remains undefined, …

Regimen for Target-controlled Infusion Decreasing Remifentanil-induced cough
연구 목적 : 본 연구는 remifentanil의 목표농도주입시 중심효과처 농도를 여러 가지 regimen으로 단계적으로 증가시켰을 때 remifentanil 유발 기침을 예방하는데 효과적인지 알아보고자 하였다. 연구 방법 : 이전 연구에서 140명의 환자들을 무작위로2군으로 나누었다. 두 군 모두 2단계의 중심 효과처 목표 농도 증가를 이용하여 remifentanil을 투여받았는데, 한 군은 1.0에서 4.0ng/ml로, 한 군은 2.0에서 4.0ng/ml로 증가시켰다. 이 연구 결과를 바탕으로 본 연구에서는 3단계의 …

Simulation of a Singular Cough Event in an Enclosed Breakroom
… This study simulates the evolution of a singular cough event in a computer modeled breakroom. In addition, another model is created to simulate the inlet conditions. This model is a detailed simulation of the inlet flow through a perforated plate covering the vent, using a k-omega SST model. This …

Cough sound discrimination in noisy and reverberant environments using microphone arrays
Cough sound discriminator algorithms are capable of distinguishing between dry and wet cough types. The performance of such algorithms, however, is affected by noise and reverberation which might exist in patients' environments. In this thesis, the performance of the previously developed cough …

Pharmacological and Non-pharmacological Prevention of Fentanyl-Induced Cough : A meta-analysis
Fentanyl-induced cough (FIC) is often observed after intravenous bolus administration of fentanyl during anesthesia induction. This meta-analysis assessed the efficacy of pharmacological and non-pharmacological interventions to reduce the incidence of FIC. We searched for randomized controlled …

A novel cough aerosol sampling device for sputum-scarce individuals with tuberculosis
… have difficulty producing this sample. A cough aerosol sampling system (CASS) can collect aerosol droplet samples for testing when sputum sampling is not possible. These systems rely on inertial impaction whereby particles are sorted based on their diameter. Thus, CASS also offers …

Comparison of the Incidence and Severity of Cough after Alfentanil and Remifentanil Injection
… of fentanyl derivatives can induce cough paradoxically. This study examined the incidence and severity of cough after a bolus of alfentanil and remifentanil. Methods: Four-hundred sixty five patients, aged 18-70 years, were allocated randomly to three groups to receive alfentanil 10 …

Acoustical and flow characteristics of a cough as an index of pulmonary function in the guinea pig
Human studies indicate that cough sound and flow analysis may be useful for diagnosing pulmonary abnormalities. The purpose of this study was to evaluate an animal model for cough sound and flow analysis. A system was designed to expose guinea pigs to aerosols of citric acid (0.39M) and record …

Sensory-Mechanical Responses to High-Dose Methacholine Bronchoprovocation: The Modulating Effects of Deep Inspirations
… variables distinguishing classic asthma (CA), cough variant asthma (CVA), and methacholine (MCh)-induced cough with normal airway sensitivity (COUGH) are incompletely understood. Defining the range of normal responses associated with deep inspirations (DIs) during high-dose MCh is key to …

"Has the patient been coughing?" Do Ugandan providers ask patients tested for malaria about cough history? Secondary analysis of 2011 data from the Integrated Infectious Disease Capacity Building Evaluation (IDCAP)
… guide health care providers to ask about cough history and perform laboratory testing for evidence of infection with malaria by either microscopy or a malaria rapid diagnostic test (RDT) in all patients suspected of having malaria. Many health workers do not adhere to these guidelines …
