The large increases in reactive nitrogen (N) deposition in developed countries since the Industrial Revolution have had a marked impact on ecosystem functioning, including declining species richness, shifts in species composition, and increased N leaching. A potential mitigation of these harmful effects is the action of N as a fertiliser, which, through increasing primary productivity (and subsequently, organic matter production), has the potential to increase ecosystem carbon (C) storage. Here we report the response of an upland heath to 10years of experimental N addition...

Surgical results in obstructive sleep apnea syndrome (OSAS) vary greatly, whatever the surgical technique or site. Most authors agree that rigorous patient selection is logical and mandatory. Drug-induced sleep endoscopy (DISE) was introduced in 1991 and has been rediscovered and used extensively since the 2000s. It attempts to mimic natural sleep in order to observe the upper airway on flexible endoscopy in a situation in which obstruction may occur. A review of the DISE literature was performed, and is reported in two parts...

Importance: Drug-induced sleep endoscopy is a diagnostic technique that allows dynamic evaluation of the upper airway during artificial sleep. The lack of a standardized procedure and the difficulties associated with direct visual detection of obstructive events result in poor intraobserver and interobserver reliability, especially when otolaryngology surgeons not experienced in the technique are involved. Objectives: To describe a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG) in patients with a diagnosis of obstructive sleep apnea syndrome and discuss the technique's possible advantages compared with the standard procedure...

Using the Self-Assessment of Perceived Level of Cultural Competence (SAPLCC) questionnaire, frequencies, means, and ANOVAS were determined to create medical and pharmacy student profiles of cultural competence. Profiles were used to identify needs for training and underscore critical issues that should be given priority in the curriculum. Significant differences were found in several domains of cultural competence (knowledge, skills, attitudes, and abilities); they may be explained by differences in the implementation of a pilot curriculum, the racial composition of students in both programs, and other characteristics...

Few data are available about the pattern of upper airway (UA) obstruction in children <2 years with obstructive sleep apnea syndrome (OSAS). Also, the role of adenoidectomy versus adenotonsillectomy (AT) is poorly defined in this age group. We performed drug-induced sedation endoscopy (DISE) in young OSAS children to investigate the pattern of UA obstruction and the value of DISE in therapeutic decision making. Retrospective analysis of ≤2-year-old children undergoing DISE-directed UA surgery. OSAS severity and the treatment outcomes were documented by polysomnography...

BACKGROUND: Adenotonsillectomy is the most commonly performed operation for pediatric snoring/sleep disordered breathing (S/SDB). However, 20-40% of patients will fail to improve. Drug-induced sleep endoscopy (DISE) may provide a more individualized surgical plan and limit unsuccessful surgeries. The aim of this study was to assess the impact of DISE on surgical decision-making in surgically naïve children with S/SDB. METHODS: A retrospective observational cohort study was undertaken at the Stollery Children's Hospital...

The use of a mandibular advancement device (MAD) increases the activity of the temporo-mandibular (TM) complex and masseter (MM) muscles with the risk of reducing treatment compliance. Predictors of treatment outcome are of importance in selecting patients who might benefit from MAD without side effects. The role of mandibular advancement (MA) during drug-induced sleep endoscopy (DISE) is controversial. In three cases (BMI < 30) affected by non-severe OSAS (AHI < 30 e/h), we recorded the surface EMG signal of MM activity during DISE...

BACKGROUND: Drug-induced sedation endoscopy (DISE) is a diagnostic procedure which allows evaluation of the collapsibility of the upper airway. According to expert opinion, it is possible to imitate nocturnal collapsibility and perform a realistic investigation of the site of obstruction and vibration. This should enable sufficient and precise therapeutic advice to be given solely on the basis of clinical assessment. OBJECTIVE: The current publication critically evaluates the present state of development of DISE and its potential indications...

PURPOSE: Manual catheter recognition remains a time-consuming aspect of high-dose-rate brachytherapy (HDR) treatment planning. In this work, a novel catheter lumen recognition algorithm was created for accurate and rapid digitization. METHODS: MatLab v8.5 was used to create the catheter recognition algorithm. Initially, the algorithm searches the patient CT dataset using an intensity based k-means filter designed to locate catheters. Once the catheters have been located, seed points are manually selected to initialize digitization of each catheter...
