Inhaled Corticosteroid Withdrawal in Chronic Obstructive Pulmonary Disease (COPD)

COPDInhaled Corticosteroid

According to the WISDOM study, withdraw of inhaled steroids has no effect on the acute exacerbation of chronic obstructive pulmonary disease (COPD), but the lung function of patients with COPD is significantly reclined. In the subgroup analysis of this study, patients with COPD were found to have continued to use inhaled steroids in patients with eosinophilic leukocytes greater than 400 cells/ul or whom has more than two episodes of exacerbation per year. However, in SUNSET study, it was pointed out that withdraw of inhaled steroids had no effect on lung function in patients with COPD, but it was also found that in patients with COPD, eosinophilic leukocytes in the blood were greater than 300 cells/ul, have a better therapeutic response in steroid inhalation. In addition, some studies have shown that in patients with COPD, a decline in lung function after discontinuation of inhaled steroids can make the patient's clinical symptoms worse and increase the risk of acute exacerbations. However, in other comprehensive analytical studies, there are different outcomes. There is no statistically significant difference in the risk of acute exacerbation in patients with COPD after discontinuation of inhaled steroids. In past studies, it was noted that inhaled steroids cause an increased risk of pneumonia in patients with COPD. However, in these studies, the diagnosis of pneumonia was only from the clinician's suspicion without clear symptom assessment, laboratory examination, microbiological evidence or imaging assessment. Therefore, further research is needed to assess whether patients are suitable for the reduction of inhaled steroids and the impact of COPD in clinical treatment.

The Cyclocapnic Method for Measurement of Chemosensitivity

Periodic BreathingHeart Failure

We aim to test our method for measuring chemosensitivity (the ventilatory response to a change in carbon dioxide), which uses sinusoidal carbon dioxide stimuli. Hypotheses: Carbon dioxide sensitivity is dependent on the cycle time over which we administer the gas (frequency). Chemoreflex gain decreases as deadspace increases.

Switching From Tobramycin Inhalation Treatment to Tobramycin Inhaler Treatment: The Effect on CF...

Alteration in Quality of Life of CF PatientsFollowing Change of Treatment From Antibiotic Inhalation to Antibiotic Inhaler

Pseudomonas is a common and virulent respiratory bacteria in patients with Cystic Fibrosis (CF). With time, the infection with Pseudomonas becomes chronic and very difficult to eradicate. The standard treatment of chronic Pseudomonas infection is inhaled Tobramycin which is given every other month.. Inhalation of Tobramycin was proven as an effective treatment that improves the respiratory function and reduces the concentration of bacteria in the sputum. However, inhaled treatment lasts between 15 to 30 minutes twice a day and therefore adherence is a major problem. The effect of switching from inhalation treatment to inhaler treatment on patient's adherence and quality of life has not been studied.

Effects of Allergen Inhalation on Adenosine Receptor Expression in Sputum and Peripheral Blood

AsthmaHealthy

The purpose of this study is to determine whether asthmatics have different adenosine receptor expression profiles than healthy controls. We hypothesize that asthmatics will have increased adenosine receptor expression versus control subjects. We also want to study the effects of allergen inhalation on adenosine receptor expression in asthmatics. We believe that adenosine receptor expression will be upregulated after allergen inhalation. Both hypotheses are being tested in sputum and peripheral blood.

Cyclosporine Inhalation Solution (CIS) in Lung Transplant Recipients

Lung Transplant

Currently there are no approved therapies for lung transplant recipients in the United States (US). Treatment with CIS following lung transplantation has previously been demonstrated to result in a clinically meaningful improvement in survival and chronic rejection-free survival compared to placebo, but additional data supporting its use is needed prior to Food and Drug Administration (FDA) approval. This treatment use protocol is a mechanism for providing eligible lung transplant recipients early access to CIS in advance of FDA approval.

A Comparison Between the Aysis® Cs2 (General Electrics) Ventilator in EtControl® Mode and the Perseus®...

Anesthetics AgentConsumption2 more

The Aysis® Cs2 ventilator offers an automated control of end-tidal inhalation anesthetic concentration, the EtControl® mode. A low Fresh Gas Flow (FGF) (0.5L/min) is kept during the maintenance of the anesthesia, decreasing the expensive consumption of halogenated agents. The Perseus® A 500 offers a VaporView® mode that gives the evolution of inspired (Fi) and end-tidal (Fe) fractions of halogenated agents for 20 minutes based on the delivered fraction (Fd). FGF remains adjusted manually by the practitioner. This mode also makes it possible to maintain a low FGF (0.5 L/min), provided the halogen Fd is set to maintain a steady Fe curve. The goal of this work was to compare the maniability of the intraoperative administered concentrations and the consumption of Desflurane between these 2 modalities of administration.

Lips and Tongue of Mouth Breathing Children

Mouth Breathing

Purpose: to characterize the posture, tone and mobility of lips and tongue of mouth breathing children. Methods: 40 mouth breathing children, 26 (65%) male and 14 (35%) female, aging between 7 and 10 years old, were involved in this research realized in São Paulo, SP, Brazil . It was used the MBGR protocol to evaluate the posture, tone and mobility of lips and tongue of mouth breathing children.
