This work proposes an automated system for real-time high-accuracy detection of cerebral embolic signals (ES) to couple with transcranial Doppler ultrasound (TCD) devices in diagnosing a risk of stroke. The algorithm employs Adaptive Gain Control (AGC) approach to capture suspected ESs in real-time. Then, Adaptive Wavelet Packet Transform (AWPT) and Fast Fourier Transform (FFT) are used to extract from them features most efficiently representing ES, which determined by Sequential Feature Selection technique...

The dyadic discrete wavelet transform (dyadic-DWT), which is based on fixed integer sampling factor, has been used before for processing piecewise smooth biomedical signals. However, the dyadic-DWT has poor frequency resolution due to the low-oscillatory nature of its wavelet bases and therefore, it is less effective in processing embolic signals (ESs). To process ESs more effectively, a wavelet transform having better frequency resolution than the dyadic-DWT is needed. Therefore, in this study two ESs, containing micro-emboli and artifact waveforms, are analyzed with the Directional Dual Tree Rational-Dilation Wavelet Transform (DDT-RADWT)...

OVERVIEW: Whilst the majority of evidence supports the adjunctive use of eicosapentaenoic acid (EPA) in improving mood, to date no study exists using low-dose docosahexaenoic acid (DHA) alone as an adjunctive treatment in patients with mild to moderate major depressive disorder (MDD). METHODS: A naturalistic 8-week open-label pilot trial of low-dose DHA, (260 mg or 520 mg/day) in 28 patients with MDD who were non-responsive to medication or psychotherapy, with a Hamilton Depression Rating Scale (HAM-D) score of greater than 17, was conducted...

In order to investigate the sleep quality and influencing factors in patients with Parkinson's disease (PD), 201 PD patients were enrolled and underwent extensive clinical evaluations. Subjective sleep evaluation was assessed using the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). It was found that poor sleep quality (77.11%) and excessive daytime sleepiness (32.34%) were commonly seen in PD patients and positively correlated with disease severity. Then 70 out of the 201 PD patients and 70 age- and sex-matched controls underwent a polysomnographic recording...

Across 5 decades, hundreds of randomized trials have tested psychological therapies for youth internalizing (anxiety, depression) and externalizing (misconduct, attention deficit and hyperactivity disorder) disorders and problems. Since the last broad-based youth meta-analysis in 1995, the number of trials has almost tripled and data-analytic methods have been refined. We applied these methods to the expanded study pool (447 studies; 30,431 youths), synthesizing 50 years of findings and identifying implications for research and practice...

Objective: To evaluate the relationships between anatomical changes and treatment outcomes after modified velopharyngeal surgery in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with the soft palate drooping. Methods: From November 2011 to November 2015, 44 OSHS patients (AHI 5-30 times/h) with the soft palate drooping determined by Muller test and drug-induced sleep endoscopy (DISE) were randomly selected. Treatment group included 23 patients who underwent modified velopharyngeal surgery, in which uvula was preserved and soft palate was shortened and advanced...

BACKGROUND: Distal bicep tendon injuries are a traumatic event though rather rare. The pathogenesis is not entirely clear. The most common cause for injury is an unexpected load on the biceps when the elbow is in an extended position. Although several studies have provided insight into the pathogenetic processes of the lesion, the literature suggests to treat all injuries surgically (whether partial or total) if there is high functional demand. METHODS: Between January 2006 and March 2016 were studied 20 patients surgically treated for a disconnected distal bicep, 15 with a total lesion and 5 with a partial lesion...

BACKGROUND: Catheter-based renal sympathetic denervation (RSD) significantly reduces blood pressure in patients with resistant hypertension, who commonly have obstructive sleep apnoea (OSA). These patients are considered particularly responsive to the antihypertensive effects of RSD, but additional benefits of metabolic control on sleep apnoea severity have not been thoroughly investigated. METHODS: The effect of RSD was evaluated prospectively in a cohort of patients with OSA (apnoea-hypopnea index (AHI) ≥15 events per hour and an Epworth Sleepiness Scale (ESS) score ≤9) and treatment resistant hypertension...

One key potential explanation for the evolution of cooperation is conditional cooperation. This allows cooperation to evolve for cooperators who switch their behavior on the basis of information about the opponent's behavior or reputation. However, information about the opponent's behavior or reputation is sometimes unavailable, and previous studies have assumed that a player cooperates with some default probability when no information about the opponent's previous behavior or reputation is available. This default probability has been interpreted as the player's "optimism"...

BACKGROUND: Sleep disruption and excessive sleepiness are the known consequences of shift work. The recent spate of night-time road and air accidents, with some being directly attributed to driver sleepiness prompted us to undertake this study. AIMS: To screen for excessive sleepiness, coping practices, and post-shift sleep hygiene in night bus drivers.

OBJECTIVES: The objective of this study was to examine the potentiating effects of performing a single sprint-style sled push on subsequent unresisted 20m sprint performance. DESIGN: Randomized crossover design. METHODS: Following a familiarization session, twenty rugby league players performed maximal unresisted 20m sprints before and 15s, 4, 8 and 12min after a single sled push stimulus loaded with either 75 or 125% body mass. The two sled push conditions were performed in a randomized order over a one-week period...

BACKGROUND: The impact of endoscopic sinus surgery (ESS) on pulmonary function in cystic fibrosis (CF) patients with chronic rhinosinusitis remains unclear, as studies have demonstrated conflicting results. To date, no study has looked specifically at the impact of CF genotype on lung function after ESS. In this study, we reviewed changes in pulmonary function test (PFT) results after ESS in F508del homozygotes and heterozygotes. METHODS: The charts of 25 patients with CF without prior lung transplant, who underwent ESS performed by the same surgeon between the period of July 2005 to July 2015, were retrospectively reviewed...

Sleep disorders are highly prevalent in the population and have dramatic health, social, and economic impacts. However, their treatments may remain symptomatic due to ignorance of molecular factors which may provide fundamental insights into the neurological bases of sleep. Excessive daytime sleepiness (EDS) is a common complaint encountered in neurological practice with significant effects both on individuals and on society. We aimed to investigate the role of monoamine oxidase A (MAOA) as a candidate gene in EDS...

BACKGROUND: Responsiveness, or sensitivity to clinical change, is important when selecting patient-reported outcome measures (PROMs) for research and clinical applications. This study compares responsiveness of PROMs used in chronic rhinosinusitis (CRS) to inform the future development of a highly responsive instrument that accurately portrays CRS patients' symptom experiences. METHODS: Adult CRS patients initiating medical therapy (MT; n = 143) or undergoing endoscopic sinus surgery after failing MT (ESS; n = 123) completed the 22-item Sino-Nasal Outcome Test (SNOT-22), European Position Statement on Rhinosinusitis (EPOS) visual analog scale (VAS), and 29-item Patient-Reported Outcomes Measurement Information System (PROMIS-29) at baseline and 3 months after treatment...

The present study investigated caffeinated beverage consumption and screen time in the association with excessive daytime sleepiness (EDS) and sleep duration. We conducted a cross-sectional study including 249 Korean male high school students. These participants responded to a questionnaire inquiring the information on lifestyle factors, consumption of caffeinated beverages, time spent for screen media, and sleep duration as well as to the Epworth Sleepiness Scale (ESS) questionnaire. EDS was defined as ESS scores of 9 or greater...
