Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

Respiratory failure following extubation causes significant morbidity and increases mortality in teh surgical intensive care unit (SICU). However the causes of respiratory failure following extubation remain poorly understood. The investigators hypothesize that extubation failure can be predicted based on preoperative risk factors as well as ICU acquired morbidities including muscle weakness and renal failure.

The purprose of this study is to develop and validate an analytical and clinical NIPD test for cystic fibrosis from maternal blood by analysis circulating free fetal DNA (cff-DNA), searching for the paternal mutation in families with CFTR compound heterozygosity

The infection is a major risk to hospitalized patients, especially those admitted to the Intensive Care Unit (ICU) and an unfavorable factor in the outcome of critically ill patients, increasing costs and prolonging hospitalization hospitalar. The ventilator-associated pneumonia (PAV) is considered the most prevalent nosocomial infection in the ICU, occurring in 9% to 68% of patients with prosthetic ventilatória.Due to the high rate of PAV and mortality related to it, is very important both prescription and administration of antibiotics correctly, as deescalation or escalation according the result of cultures.Therefore, the objectives of this study is assess if whether the antibiotic prescribed of ventilator-associated pneumonia following the orientation of literature. Will also be assessed the rate of PAV in patients critically ill adults, the main microorganisms responsible by PAV and determining antimicrobial susceptibility.

Herpes esophagitis presents a clinical diagnostic challenge. The investigators report the first case of herpes esophagitis presenting as vocal fold palsy in an immunocompetent host. The investigators case highlights the importance of performing a detailed laryngoscopic examination in any patient with prolonged husky voice.

The purpose of this study is to determine the appropriate concentration of diagnostic reagent of house dust mite (Dp) to be used in diagnostic allergy skin prick test among Thai population with allergic rhinitis.

Background: Persistent severe pulmonary hypertension (PH) after mechanical valve replacement is a frequent finding in patients with severe valve-diseases. The reasons to develop PH are multifactorial and the prevalence of severe PH significantly worsens the patients´ outcome. Aims: (i) To define the prevalence of PH in patients after valve replacement and (ii) to identify factors predicting persistent PH. Methods: All patients which underwent valve replacement at our institution between the years 2008 -2010 will be screened retrospectively. Those patients with pre- procedural proven PH by means of right-heart catheterization will receive prospective follow-up with echocardiography. Diagnosis of persistent PH will be confirmed with right heart catheterization.

A 15-gene lung signature was created to identify predictive and prognostic biomarkers for Non-Small Cell Lung Cancer (NSCLC) patients. The 15-gene signature was validated using a microarray platform with fresh frozen tumor tissue to place NSCLC patients into high risk and low risk cohorts with significantly different survivals. Using fresh frozen tissue can be challenging, so this study attempts simplify the process by migrating the 15-gene signature from fresh frozen to two alternative tissue formats: Formalin Fixed Paraffin Embedded (FFPE) and RNAlater. The gene expressions of the different tissue formats will be compared to see if the fresh frozen tissue results are similar to the alternative tissue formats.

Registry to follow patients with sarcoidosis associated pulmonary hypertension

The goal of this study is to investigate acute respiratory distress syndrome (ARDS) and septic lung with positron emission tomography (PET) imaging and to examine the distribution of inflammation, as measured by neutrophil metabolic activity.

Energy expenditure (EE) in critically ill patients is highly variable depending on the initial severity of the disease and treatments. Clinicians need to measure EE by indirect calorimetry (IC) to optimize nutritional support. IC devices available on the market have insufficient accuracy for clinical and research use. A new IC is being developed to meet these needs. Objectives: Validation of a reliable and easy-to-use IC device. Primary objective: • Accuracy of EE measurements (kcal/d measured over 30 min) of the new and the reference IC devices in intubated ICU patients on mechanical ventilation Secondary objectives: Accuracy of EE measurements in ICU patients of spontaneous breathing Accuracy of EE measurement during ~30 min. vs. the sum of 6 periods of 60 min/12 hrs Accuracy of EE measurements in ICU patients on non-invasive mechanical ventilation Design: Prospective, controlled, observational multicenter study. Subjects: 182 ICU patients.
