The extent to which the sleeping brain processes sensory information remains unclear. This is particularly true for continuous and complex stimuli, such as speech, in which information is organized into hierarchically embedded structures. Recently, novel metrics for assessing the neural representation of continuous speech have been developed, using non-invasive brain recordings. Those were so far tested during wakefulness. Here we investigated, for the first time, the sleeping brain's capacity to process continuous speech at different hierarchical levels, using a newly developed Concurrent Hierarchical Tracking (CHT) approach that can online monitor the neural representation and processing-depth of continuous speech...

BACKGROUND: Dengue fever is a major public health problem with an increased incidence in recent years. Gall bladder wall thickening has been reported as one of the most common findings in dengue fever. There is a paucity of literature regarding the various patterns of gall bladder wall thickening in dengue fever and their significance in predicting the severity of disease. METHODOLOGY AND SIGNIFICANT FINDINGS: Out of 93 seropositive patients included in the study, 54 patients with dengue fever had gall bladder wall thickening...

BACKGROUND: There is a paucity of data in the literature regarding end-of-life care and do-not-resuscitate (DNR) status of the pediatric surgical patient, although invasive procedures are frequently performed in very high risk and critically ill children. Despite significant efforts in adult medicine to enhance discussions around end-of-life care, little is known about similar endeavors in the pediatric population. METHODS: A retrospective review of the National Surgical Quality Improvement Program Pediatric database was performed...

Thoracic ossification of the ligamentum flavum (TOLF) complicated with dural ossification (DO) is a severe clinical disease. The diagnosis of DO preoperatively remains challenging. The current study retrospectively analyzed imaging features of 102 segments with TOLF from 39 patients and proposed a grading system for evaluating DO risk. Logistic regression results showed that unilateral spinal canal occupational rate (UCOR), tram track signs, and C-signs were all risk factors for DO (odds ratios of 5.393, 19...

Inflammatory bowel disease (IBD) is an established risk factor for cardiovascular disease (CVD). However, whether cardiac consequences present early in IBD is unknown. This is the first study in children aiming to unmask altered myocardial mechanics in IBD. We enrolled 50 consecutive normotensive children with Crohn's disease (CD) (n = 28) or ulcerative colitis (UC) (n = 22). The study groups consisted of 18 patients with active inflammatory disease (mean age 14.6 ± 2.5 years) and 32 children with IBD in remission (14...

Instability of the patella is a common cause of knee pain and dysfunction in pediatric and adolescent patients and can be due to several factors. Although some patients will recall a specific traumatic event others may not, requiring the diagnosis to be made on the basis of physical examination and imaging. Congenital dislocation and connective tissue disorders should also be considered, even in the setting of trauma. There are radiographic parameters that may identify causes of instability such as trochlear and patellar abnormalities, and magnetic resonance imaging can identify signs of trauma such as bony edema, loose osteochondral fragments, and increased tibial tubercle-trochlear groove distance...

Cities are expected to play a major role in carbon emissions mitigation. A key step in decoupling carbon emissions from urban economy is to understand the impact of socioeconomic development on urban metabolism over time. Herein, we establish a system-based framework for modeling the variation of urban carbon metabolism through time by integrating a metabolic flow inventory, input-output model and network analysis. Using Beijing as a case study, we track the historical trajectory of carbon flows embodied in urban final consumption over 1985-2012...

Communication provides the basis for social life. In ant colonies, the prevalence of local, often chemically mediated, interactions introduces strong links between communication networks and the spatial distribution of ants. It is, however, unknown how ants identify and maintain nest chambers with distinct functions. Here, we combine individual tracking, chemical analysis and machine learning to decipher the chemical signatures present on multiple nest surfaces. We present evidence for several distinct chemical 'road-signs' that guide the ants' movements within the dark nest...

Iconic mappings between words and their meanings are far more prevalent than once estimated and seem to support children's acquisition of new words, spoken or signed. We asked whether iconicity's prevalence in sign language overshadows two other factors known to support the acquisition of spoken vocabulary: neighborhood density (the number of lexical items phonologically similar to the target) and lexical frequency. Using mixed-effects logistic regressions, we reanalyzed 58 parental reports of native-signing deaf children's productive acquisition of 332 signs in American Sign Language (ASL; Anderson & Reilly, 2002) and found that iconicity, neighborhood density, and lexical frequency independently facilitated vocabulary acquisition...

An independent press that is free from government censorship is regarded as instrumental to ensuring human rights protection. Yet governments across the globe often target journalists when their reports seem to offend them or contradict their policies. Can the government's infringements of the rights of journalists tell us anything about its wider human rights agenda? The killing of a journalist is a sign of deteriorating respect for human rights. If a government orders the killing of a journalist, it is willing to use extreme measures to eliminate the threat posed by the uncontrolled flow of information...

The minimal amount known regarding chromosomal microduplications and microdeletions presents a fascinating new direction of research into better understanding misunderstood symptoms and overall genomic influence. Specifically, the 16p11.2 microduplication has been associated with a myriad of possible cognitive, physical, and emotional symptoms. The purpose of this study is to inform the reader of the biological basis of the 16p11.2 microduplication, review sources that suggest a link between the microduplication and clinically relevant diagnoses/sources of impairment, and to better understand the implications and development of symptoms through the illustration of a case example...

BACKGROUND: Children subjected to traumatic events during childhood are reported to exhibit behavioral and cognitive deficits later in life, often leading to post-traumatic stress disorder (PTSD) and major depression. Interestingly, some children continue to remain normal despite being exposed to the same risk factors. These trauma-related behavioral and cognitive profiles across different stages of life are not well understood. Animal studies can offer useful insights. OBJECTIVE: The goal of this study was to determine the impact of early life exposure to traumatic events on behavioral and cognitive profile in rats by tracking the behavior of each rat at different ages...

Self-monitoring of lung function, vital signs, and symptoms is crucial for lung transplant recipients (LTRs) to ensure early detection of complications and prompt intervention. This study sought to identify patterns and correlates of adherence to self-monitoring among LTRs over the first 12-months post-discharge from transplant. This study analyzed existing data from the usual care arm participants of a randomized clinical trial who tracked self-monitoring activities using paper-and-pencil logs. Adherence was calculated as the percent of days LTRs recorded any self-monitoring data per interval: hospital discharge-2 months, 3-6 months, and 7-12 months...

AIM: Propofol is a widely used anesthesia induction agent and is easily accessible in most healthcare facilities. Unlike regulated or schedule drugs, propofol is inconsistently tracked, leading to inaccurate inventories, incorrect billing, and unrecognized diversion. The goal of this project was to implement a new method of tracking propofol in a single setting, with the aim of accounting for 100% of the drug. METHODS: For two, 2-week observation periods, data were extracted from an automated medication management system or pharmacy inventory system, anesthesia records, and pharmacy billing sheets for cases in a Gastrointestinal (GI) Endoscopy Unit, and compared pre-implementation and post-implementation of a new tracking and accounting protocol...

Mast cells are resident immune cells in the thalamus that can degranulate and release hundreds of signaling molecules (i.e., monoamines, growth factors, and cytokines) both basally and in response to environmental stimuli. Interestingly, mast cell numbers in the brain show immense individual variation in both rodents and humans. We used a Pavlovian conditioned approach (PCA) procedure to examine whether mast cells are associated with individual variation in the attribution of incentive-motivational value to reward-related cues...

BACKGROUND: To investigate the potential of human satellite cells in muscle regeneration small animal models are useful to evaluate muscle regeneration. To suppress the inherent regeneration ability of the tibialis muscle of mice before transplantation of human muscle fibers, a localized irradiation of the mouse leg should be conducted. We analyzed the feasibility of an image-guided robotic irradiation procedure, a routine treatment method in radiation oncology, for the focal irradiation of mouse legs...

The autopsy is an integral part of the service of a large academic pathology department. Timely reporting is central to providing good service and is beneficial for many stakeholders, including the families, the clinical team, the hospital, and the wider community. The current study aimed to improve hospital-consented autopsy reporting times (turnaround time, TAT) by using lean principles modified for a healthcare setting, with an aim of signing out 90% of autopsies in 90 days. An audit of current and historical TATs was performed, and a working group incorporating administrative, technical, and professional staff constructed a value stream map documenting the steps involved in constructing an autopsy report...

REVIEW

Environmental stimuli that reliably accompany alcohol intake can become associated with the pharmacological effects of alcohol through classical (Pavlovian) conditioning. Of growing interest to addiction researchers is whether or not this process results in the attribution of incentive salience to alcohol-predictive cues, which could motivate alcohol-seeking behavior and relapse. To evaluate this question, we present a review of rodent behavioral studies that examined the capacity of alcohol-predictive cues to (i) support sign-tracking behavior, (ii) serve as conditioned reinforcers, and (iii) produce Pavlovian-to-instrumental transfer...
