OBJECTIVE: Obstructive Sleep Apnea (OSA) is a serious chronic disease and a risk factor for cardiovascular diseases. Snoring is a typical symptom of OSA patients. Knowledge of the origin of obstruction and vibration within the upper airways is essential for a targeted surgical approach. Aim of this paper is to systematically compare different acoustic features, and classifiers for their performance in the classification of the excitation location of snore sounds. METHODS: Snore sounds from 40 male patients have been recorded during Drug-Induced Sleep Endoscopy, and categorized by ENT experts...

Importance: Persistent postconcussion symptoms (PPCS) pose long-term challenges and can negatively affect patients' health-related quality of life (HRQoL). To date, no large comprehensive study has addressed the association between PPCS and HRQoL. Objectives: To determine the association between HRQoL and PPCS at 4 weeks after concussion and assess the degree of impairment of HRQoL in the subsequent 12 weeks. Design, Setting, and Participants: In a prospective, multicenter cohort study (Predicting Persistent Postconcussive Problems in Pediatrics [5P]) from August 14, 2013, to September 30, 2014, children aged 5 to 18 years who presented to the emergency department within 48 hours after head injury and were considered to have an acute concussion were enrolled across 9 pediatric emergency departments within the Pediatric Emergency Research Canada Network...

For many years, there has been confusion about the role that nutrition plays in inflammatory bowel diseases (IBD). It is apparent that good dietary advice for one individual may prove inappropriate for another. As with many diseases, genome-wide association studies across large collaborative groups have been important in revealing the role of genetics in IBD, with more than 200 genes associated with susceptibility to the disease. These associations provide clues to explain the differences in nutrient requirements among individuals...

BACKGROUND: Beta-blockers (BBs) are the mainstay prognostic medication for all stages of chronic heart failure (CHF). There are many classes of BBs, each of which has varying levels of evidence to support its efficacy in CHF. However, most CHF patients have one or more comorbid conditions such as diabetes, renal impairment, and/or atrial fibrillation. Patient enrollment to randomized controlled trials (RCTs) often excludes those with certain comorbidities, particularly if the symptoms are severe...

In the present study, the heads of 11 normal subjects and 21 patients affected by hydrocephalus due to three different causes were simulated using fluid-structure interaction (FSI). To validate the results, the calculated diagram of CSF velocity in aqueduct of Sylvius (AS) was compared with the similar velocity diagram measured using Cine PC-MRI for the same subject. After ensuring the agreement of results, other outputs such as CSF pressure were calculated non-invasively using FSI. The intracranial pressure and CSF pressure in AS and behind the optic nerve sheath were in patients 5-5...

BACKGROUND/PURPOSE: The aims of the current study were to determine whether patients with conduct disorder (CD) showed an abnormal availability of serotonin reuptake transporter (SERT), and if their hyperkinetic symptoms, impulsivity, and quality of life were correlated with the availability of SERT. METHODS: We recruited 14 drug-naïve patients with CD and eight age-matched healthy controls (HCs). The adult attention-deficit/hyperactivity disorder (ADHD) self-report scale (ASRS), Barrett impulsivity scale (BIS), and the World Health Organization quality of life-brief version (WHOQOL-BREF) scale were administered...

The VA has integrated psychologists and other licensed mental health providers, known collectively as co-located collaborative care (CCC) providers, into patients' primary care medical homes to improve mental health services for veterans. However, it is unclear if CCC providers are routinely using mental health measures as part of evidence-based, coordinated care. This study aimed to determine the prevalence and predictors of CCC provider utilization of brief, validated measures. A retrospective review of VA electronic medical records from 8403 veterans diagnosed with depression, posttraumatic stress disorder, or anxiety disorder was conducted...

The French Society of Research and Sleep Medicine (SFRMS) organized a meeting on obstructive sleep apnea syndrome (OSAS) in children. A multidisciplinary group of specialists (pulmonologist, ENT surgeons, pediatricians, orofacial myofunctional therapists, neurophysiologists, and sleep specialists) reached a consensus on the value of isolated or clustered clinical symptoms and of questionnaires completed by parents in the clinical diagnosis and in assessing the severity of OSAS. Are clinical history with validated questionnaires and a rigorous physical examination sufficient to suspect OSAS, to appreciate its severity, and finally to confirm the diagnosis? Usually, a sleep recording of respiratory parameters remains mandatory for the diagnosis of OSAS to be made...

BACKGROUND: A recent hypothesis has suggested that core deficits in goal-directed behavior in obsessive-compulsive disorder (OCD) are caused by impaired frontostriatal function. We tested this hypothesis in OCD patients and control subjects by relating measures of goal-directed planning and cognitive flexibility to underlying resting-state functional connectivity. METHODS: Multiecho resting-state acquisition, combined with micromovement correction by blood oxygen level-dependent sensitive independent component analysis, was used to obtain in vivo measures of functional connectivity in 44 OCD patients and 43 healthy comparison subjects...

BACKGROUND: Assessing primary rehabilitation needs in patients with acquired brain injury is a challenge due to case complexity and the heterogeneity of symptoms after brain injury. The Rehabilitation Complexity Scale-Extended (RCS-E) is an instrument used in assessment of rehabilitation complexity in patients with severe brain injury. The aim of the present study was to translate and test the face validity of the RCS-E as a referral tool for primary rehabilitation. Face validity was tested in a sample of patients with acquired brain injury...

BACKGROUND: Numerous factor analytic studies consistently support a distinction between two symptom domains of attention-deficit/hyperactivity disorder (ADHD), inattention and hyperactivity/impulsivity. Both dimensions show high internal consistency and moderate to strong correlations with each other. However, it is not clear what drives this strong correlation. The aim of this paper is to address this issue. METHOD: We applied a sophisticated approach for causal discovery on three independent data sets of scores of the two ADHD dimensions in NeuroIMAGE (total N = 675), ADHD-200 (N = 245), and IMpACT (N = 164), assessed by different raters and instruments, and further used information on gender or a genetic risk haplotype...

BACKGROUND: The expanded disability status scale (EDSS) is a validated and reliable tool to assess the extent of disabilities in patients with multiple sclerosis (MS). However, the use of this tool has been found to be limited in assessing various symptoms of MS that are important. Our study aimed at evaluating the efficacy of a new scoring system, reverse nutech functional score (RNFS) as compared to EDSS in assessing patients with MS treated with human embryonic stem cell (hESC) therapy...
