We provided a detailed description of our TLBC technique and highlighted areas of similarity and differences among comparative studies and attest that TBLC is a safe alternative to SLB in the diagnosis of ILD. Our data also indicated the tendency for moderate-to-severe bleeding occurred more in the endoscopy suite.
Airway stents are used to keep airways open for those patients symptomatic from tracheobronchial disease. Tracheobronchial disease or central airway obstruction (CAO) can occur with benign or malignant disease, or complications from lung transplantation. Although stents can offer symptomatic relief for CAO, complications such as granulation tissue formation, stent fracture, and infection commonly occur after stent placement. Currently, all airway stents promote mucus buildup which can lead to stent failure and airway complications. In this paper, we demonstrate the use of special anti-fouling coatings to prevent mucus buildup. The coatings have been tested: 1) for wettability, 2) using XPS and TOF-SIMS to characterize surface properties, and 3) in the laboratory (in vitro) to study effects of mucin incubation. Findings include significant improvement in limiting mucus adhesion in a lab model.
Purpose:To evaluate the impact of nurse-regulated feedings (NRFs) on growth velocity and weight gain of 1200–1500 g preterm infants.Subjects:Cohort 1: All preterm infants 1200–1500 g between 1997 and 2001 not on NRF protocol; Cohort 2: All preterm infants 1200–1500 g between 2003 and 2006 on NRF protocol. Both cohorts screened out for small gestation age, major congenital anomalies, intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), culture positive infection at birth, meningitis, and those requiring surgery.Materials and Methods:A before and after matched cohort study was conducted in the years 1997–2001 and 2003–2006, enrolling infants from Covenants Neonatal Intensive Care unit (Level III) using these studies screening protocol. Data on first 62 enrolling infants from both cohorts were used for this study. Both cohorts were matched using gestational age, birth weight, length of stay, initial length. A modified data tool collection set was used for collecting and analyzing nutritional data, this included intake (cal/kg/d, cc/kg/d, and total intake in cc) and route (initial parenteral feedings, mixed parenteral and enteral feedings, full enteral feedings), NRF, and non-NRF (NNRF). Data collection continued until discharge, initiation of adlib feeding, or greater than 50% of nutrition from breast.Discussion:Of the entire population sampled from 1997 to 2006, there were only 59 for NRF and 58 for NNRF. The mean growth velocity (g/kg/d) to reach full enteral feedings for both cohorts was insignificant (t=0.233; P=0.816). This suggested both groups were well matched up to the point of NRF institution for the 2003–2006 cohort years.Results:NRF had a 71% greater growth velocity than NNRF (P<0.001, t=6.618) at the time of discharge, initiation of adlib feeding, or greater than 50% of nutrition from breast.Conclusions:This study demonstrated that the NRF protocol offers a significant advantage in nutritional support than previous feeding regimens in this institution.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is now a standard of care to sample mediastinal lymph nodes and masses with high diagnostic accuracy and low complication rates. However, the procedure has potential complications that might be life-threatening. Here, we present the first case of Propionobacterium acnes (P. acnes) causing mediastinitis following EBUS-TBNA of a subcarinal lymph node.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
