Ventilation inhomogeneity, measured using multiple breath washout (MBW), reflects small airway function and has emerged as a valuable tool in cystic fibrosis (CF). Improved sensitivity to detect early lung damage has been suggested from preschool children through to adults and confirmed in high-resolution CT (HRCT) studies. Longitudinal utility is now emerging. A large number of parameters refl...

Abstract Objectives: to analyze the variation in incidence rates of congenital syphilis according spatial distribution Life Condition Index (LCI) among neighborhoods city Recife-PE. Methods: an ecological study, developed from 3,234 cases notified Sistema de Informação Agravos Notificação (Severe Disease Notification Information System), between 2007 and 2016. LCI was built seven variables rela...

RATIONALE High resolution computed tomography (HRCT) is a more sensitive tool for detecting early cystic fibrosis (CF) lung disease than either spirometry or plain radiography, but its relationship to other measures of lung function has not been established in young children. OBJECTIVES (1) To assess whether the lung clearance index (LCI) derived from multiple breath inert-gas washout (MBW) i...

We describe the design, construction, and application of what are believed to be the smallest fiber-optic probes used to date during imaging or diagnosis involving low-coherence interferometry (LCI). The probes use novel fiber-optic gradient-index (GRIN) lenses fabricated by a recently developed modified chemical-vapor-deposition (MCVD) process that avoids on-axis aberrations commonly marring M...

Optical spectroscopy was used to evaluate the transformation of nuclear morphology associated with intraepithelial neoplasia in an animal model of carcinogenesis. In this pilot study, we have assessed the capability of angle-resolved low-coherence interferometry (a/LCI) to monitor in situ the neoplastic progression of hamster trachea epithelial tissue. By using the depth resolution made possibl...

Lung clearance index (LCI) is a potential clinical outcome marker in bronchiectasis. Its responsiveness to therapeutic intervention has not been determined. This study evaluates its responsiveness to a session of physiotherapy and intravenous antibiotic treatment of an exacerbation.32 stable and 32 exacerbating bronchiectasis patients and 26 healthy controls were recruited. Patients had LCI and...

The lattice conditional independence (LCI) model N(C)<) is defined to be the set of all normal distributions N(O, E) on IR I such that for every pair L, M E 1<, XL and xM are conditionally independent given xLnM (ct , [AP] (1993a)). Here C)< is a ring of subsets (hence a distributive lattice) of the finite index set I such that 0, IE ".K, while for K E 1<, XK is the coordinate projection of x E...

BACKGROUND Propofol is commonly used in children undergoing diagnostic interventions under anaesthesia or deep sedation. Because hypoxaemia is the most common cause of critical deterioration during anaesthesia and sedation, improved understanding of the effects of anaesthetics on pulmonary function is essential. The aim of this study was to determine the effect of different levels of propofol a...

Prey environment, feeding success and condition of blue whiting Micromesistius poutassou larvae were analysed in contrasting meteorological situations west of Ireland in the spring of 2 consecutive years (1994 and 1995). While larval abundance in both years of the study was approximately equal, there were marked differences in the physical and biological environment between the 2 years. 1994 wa...

Background: Multiple breath inert gas washout (MBW) has been suggested as a tool for detecting early cystic fibrosis (CF) lung disease. A study was undertaken to compare the relative sensitivity of MBW and spirometry for detecting abnormal lung function in school age children with CF and to compare MBW results obtained from healthy children in the UK with those recently reported from Sweden. Me...
