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

The purpose of the study is to assess seroprevalence of COVID-19 infection in a cohort of HIV + patients and in a cohort of patients taking PrEP by emtricitabine / tenofovir.

Lifespan Cancer Institute serves over 50% of cancer patients in the state. Rhode Island is known for strong medical care and high rates of cancer screening with mammography and colonoscopy. However, cancer screening has plummeted during the COVID-19 pandemic, in part to closing physician offices and stopping non-urgent medical procedures. In addition, anecdotal reports suggest the public remains concerned about returning to physician's offices and risking possible exposure to COVID-19. As in the United States as a whole, COVID-19 has disproportionately impacted ethnic and minority individuals within underserved communities; and in Rhode Island, African Americans, Hispanics and undocumented individuals living in communities such as Central Falls, Pawtucket, Providence, East Providence and North Providence have had the highest rate of COVID-19. These communities are also impacted by healthcare disparities to access and affordability of healthcare, and as such, may be among the least likely to resume cancer screening. The Lifespan Cancer Institute will institute a project to address health disparities in cancer screening during the pandemic through the use of a targeted campaign involving social media. The goals will be to re-establish screening in the era of COVID-19 and ensure timeliness of care for those found to be at risk, or are positive for, cancer.

The chances of survival in premature babies, especially in babies born under 28 weeks, have increased in recent years, and comorbidities also increase. Bronchopulmonary dysplasia (BPD), one of the premature problems, is one of them. After a while, babies with heavy BPD are discharged with the support of a home-type mechanical ventilator by opening a tracheostomy. Tracheostomy procedure is performed by specialist doctors of otolaryngology under general anesthesia in the operating room conditions in newborns. Complications of this procedure such as bleeding, skin necrosis, decanulation, trachea laceration and infection in the early period can be seen. In the long term, in addition to complications such as formation of tracheal granulation tissue, ulceration, laceration due to the procedure, babies with tracheostomy may develop nutrition and speech problems and neurodevelopmental problems. In the literature, there is no comprehensive clinical follow-up study involving early and late clinical results related to newborns undergoing tracheostomy. In this study, early and late follow-up results (indications, anthropometric measurements, mechanical ventilation and oxygen deposition times, complications, tracheostomy closure times, tracheostomy closure times, neurodevelopmental patients in the Neonatal Intensive Care Unit of Hacettepe University Ihsan Dogramaci Children's Hospital. results, accompanying other comorbidities, etc.).

This study retrospectively evaluates clinical parameters and outcome of patients with advanced stage non-small cell lung cancer treated with neoadjuvant therapy followed by curative-intent surgery at the Divison of Thoracic Surgery at the Medical University of Vienna

Approximately 15% of patients with SARS-CoV-2 infection / COVID-19 develop a severe clinical course. This leads to hospitalization and potentially life threatening complications such as pneumonia and respiratory failure. Predictors for early detection and risk stratification are urgently needed. Moreover, only scarce information is available for long-term follow-up and late complications associated with infection. We therefore aimed to find predictors for severe courses of the novel disease as well as to establish strategies for therapeutic monitoring and follow-up.

The investigating group aims at performing an observational, prospective study that involves the evaluation of circulating biomarkers predictive of clinical evolution in patients suffering from COVID-19 disease. In particular, the aim will be to verify whether there are transcripts or cytokines / chemokines in peripheral blood, modulated differently in patients with COVID-19, distinguished on the basis of the evolution towards more severe clinical pictures that require patient intubation or that show signs of cardiovascular damage. The study will be based on the transcriptional analysis of the entire genome and serum protein to evaluate the expression of a broad spectrum of cytokines and chemokines. Genome analysis will allow the genotype to be correlated to the identified gene expression profiles.

The p63 gene is a recently discovered member of the p53 family located at chromosome 3q27Many studies have reported that overexpression of p63 can mimic p53 activities by binding DNA, activating transcription, and inducing apoptosis. Various studies proved p63 as a marker of basal cells in normal salivary glands, breast, prostate, respiratory and squamous epithelia, and of tumor cells from various malignancies. Still, p63 has been the subject of relatively few studies in lung adenocarcinoma, and breast carcinoma, and no study has described the correlation of p63 with pancreatic ductal adenocarcinoma. In the current study, we aim to evaluate the prognostic value of the expression of p63 in the lung adenocarcinoma, breast adenocarcinoma, and pancreatic ductal adenocarcinoma. We will achieve this aim by collecting clinical data retrospectively from the patients' medical records as well as assessing the histological sections and performing immunohistochemical staining for p63.

The goal of this project is to find a marker expression that the investigators can use to trace symptom progression and develop a more efficient therapy to enhance ARDS patient survival rate and better post-ICU life quality.

This is part 2 of the #NCT01618240 under the same IRB protocol #2010P001919. The primary objective of this study is to examine factors that are related to sleep-disordered breathing and upper airway patency in critically ill patients who have been recently mechanically ventilated. Our primary hypothesize is that sedatives and neuromuscular blocking agents given in the ICU prior to extubation and during the first night following extubation are associated with sleep-disordered breathing. The secondary hypotheses are that duration of mechanical ventilation, BMI, and muscle strength are associated with sleep-disordered breathing during the night after extubation. The secondary objective is to evaluate if sleep-disordered breathing in the ICU can be predicted by standard pulmonary function testing in the ICU.

To assess response to bronchodilation with tiotropium plus salbutamol in patients with severe emphysema and analyze relationships between bronchoreversibility response and semiquantitative computed-tomography based emphysema severity measures.
