Conventional sleep analysis relies primarily on electroencephalogram (EEG) waveform features assessed in concert with eye movements, respiration and muscle tone. We explore a complementary "complexity domain" approach based on multiscale entropy (MSE) analysis of EEG signals and discuss its relationships to standard sleep analysis and to that based on electrocardiogram (ECG)-derived cardiopulmonary coupling (CPC). We observe a progressive decrease in complexity associated with decreased arousability, as measured by both conventional sleep scoring and CPC analysis...

BACKGROUND: Periprosthetic hip infection treatment remains a significant challenge for orthopedics. Some studies have suggested that methicillin resistance and gram-negative organism type are associated with increased treatment failure. The aim of this research is to determine if specific organisms were associated with poor outcomes in treatment for hip periprosthetic infection. METHODS: Records were reviewed of all patients between 2005 and 2015 who underwent treatment for infected partial or total hip arthroplasty...

PURPOSE: ICDs can improve survival in at-risk patients but no consensus exists with respect to their impact on health-related quality of life (QOL). Moreover, the data are unclear on QOL benefits in specific patient subgroups. We sought to analyze, in the INTRINSIC RV ICD trial population, health-related QOL longitudinally following ICD implant and consider impact of age, gender, and ICD shocks on QOL by employing a global measure of health-related QOL. METHODS: One thousand five hundred thirty patients had an ICD implanted...

Recidivism, repeated criminal behavior after conviction and correction of prior offenses, is a costly problem across the nation. However, the contribution of empathy in determining the risk of recidivism has received limited attention, although lack of empathy has been related to antisocial personality disorder in various studies. Studies linked testosterone to aggression, antisocial behavior, and criminality, and evidence support hormonal connections between empathy and aggression. Adult male prison inmates convicted of violent or nonviolent offenses were included in a cross-sectional study of empathy, antisocial behavior, salivary testosterone, and recidivism...

In this prospective study, 15 patients received 15 variable-thread tapered implants placed in fresh extraction sites in the maxillary esthetic zone and immediately were provisionalized out of occlusion. Of the 15 patients, 11 completed their 2-year follow-up. At 2 years, the success and cumulative survival rates were both 100%, and the mean bone level gain was 0.83 mm. Soft tissue assessment showed no zero esthetic scores, improved papilla indices, and low bleeding on probing and plaque accumulation. Overall, the study implants showed excellent hard tissue, soft tissue, and esthetic outcomes, indicating a healthy tissue response in single-tooth extraction sites in the maxillary esthetic zone...

BACKGROUND: Levodopa/carbidopa intestinal gel therapy (LCIG) can efficiently improve several motor and non-motor symptoms of advanced Parkinson's disease (PD). The recently developed Movement Disorder Society-sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) improved the original UPDRS making it a more robust tool to evaluate therapeutic changes. However, previous studies have not used the MDS-UPDRS and the Unified Dyskinesia Rating Scale (UDysRS) to assess the efficacy of LCIG...

BACKGROUND: The progression of cervical kyphosis due to injury to the facet joints and musculature is a major concern for posterior foraminotomy especially for patients with cervical lordosis of less than 10°. However, cervical hypo-lordosis (cervical lordosis < 10°) may be improved with the alleviation of pain and muscle spasms, which corresponds with the disappearance of a positive Spurling's test. When surgery is necessary, the spontaneous recovery of cervical curvature may be minimally offset using minimally invasive surgical techniques, such as posterior percutaneous endoscopic cervical foraminotomy (P-PECF)...

BACKGROUND: Fracture is a complex trait, affected by both genetic and environmental factors. A meta-analysis of genome-wide association studies (GWASs) identified multiple bone mineral density (BMD) and fracture-associated loci. OBJECTIVE: We conducted a study to evaluate whether fracture genetic risk score (Fx-GRS) and bone mineral density genetic risk score (BMD-GRS) modify the association between the intake of calcium with vitamin D (CaD) and fracture risk. DESIGN: Data from 5823 white postmenopausal women from the Women's Health Initiative CaD randomized trial were included...

: Anesthetic management of orthotopic liver transplantation (OLT) is complex. Given the unequal distributions of liver transplant surgeries performed at different centers, anesthesiology providers receive relatively uneven OLT training and exposure. One well-suited modality for OLT training is the "serious game", an interactive application created for the purpose of imparting knowledge or skills, while leveraging the self-motivating elements of video games. We therefore developed a serious game designed to teach best practices for the anesthetic management of a standard OLT and determined if the game would improve resident performance in a simulated OLT...

OBJECTIVES: Proficiency in fundamental movement skills (FMS) is positively correlated with cardiorespiratory fitness, healthy weight status, and physical activity. Many instruments have been developed to assess FMS in children. It is important to accurately measure FMS competency in adolescent populations, particularly in girls, who are less proficient than boys. Yet these tests have not been validated or tested for reliability among girls in this age group. DESIGN: The current study tested the concurrent validity and reliability of two FMS assessment instruments; the newly developed Canadian Agility and Movement Skill Assessment (CAMSA), against the Victorian FMS Assessment from Australia, among a sample of early adolescent girls...

BACKGROUND: Alcoholism is a chronic relapsing disorder with complex behavioral and functional heterogeneity. To date, attempts to characterize subgroups of alcohol-dependent (AD) individuals have largely been focused on categorical distinctions based on behaviors such as ability to abstain, age of onset, and drinking motives, but these have failed to yield predictors of treatment response and disease course. The distinction between AD individuals who are or are not interested in treatment holds significant implications for interpreting results of human laboratory studies with nontreatment seekers and clinical trials with treatment-seeking AD patients...
