Jennifer A Heissel, Patrick T Sharkey, Gerard Torrats-Espinosa, Kathryn Grant, Emma K Adam
The data combine objectively measured sleep and thrice-daily salivary cortisol collected from a 4-day diary study in a large Midwestern city with location data on all violent crimes recorded during the same time period for N = 82 children (Mage  = 14.90, range = 11.27-18.11). The primary empirical strategy uses a within-person design to measure the change in sleep and cortisol from the person's typical pattern on the night/day immediately following a local violent crime. On the night following a violent crime, children have later bedtimes...

We report the case of a 36-year-old woman with a subarachnoid haemorrhage (SAH) caused by a rupture of a right-sided middle cerebral artery aneurysm and subsequent malignant infarction of the right hemisphere leading to a persistent vegetative state and severe spastic tetraparesis with recurrent myocloni. Nine months after disease onset, the patient was transferred to our department for diagnostic and therapeutic re-evaluation. The poor clinical condition could not be explained by the brain lesion caused by the SAH or infarction...

After blunt trauma, certain CT markers, such as free intraperitoneal air, strongly suggest bowel perforation, whereas other markers, including free intraperitoneal fluid without solid organ injury, may be merely suspicious for acute injury. The present study aims to delineate the safety of nonoperative management for markers of blunt bowel or mesenteric injury (BBMI) that are suspicious for significant bowel injury after blunt trauma. This was a retrospective review of adult blunt trauma patients with abdominopelvic CT scans on admission to a Level I trauma center between 2012 and 2014...

OBJECTIVES: Patients with poorly controlled diabetes mellitus may have a sentinel emergency department (ED) visit for a precipitating condition prior to presenting for a hyperglycemic emergency, such as diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS). This study's objective was to describe the epidemiology and outcomes of patients with a sentinel ED visit prior to their hyperglycemic emergency visit. METHODS: This was a 1-year health records review of patients≥18 years old presenting to one of four tertiary care EDs with a discharge diagnosis of hyperglycemia, DKA, or HHS...

Oncology nurses are tasked with developing skills that enable vigilant risk surveillance through situational awareness. However, care distractions, task interruptions, increased workloads, and time constraints are common challenges that compete with the ability to provide optimal safe care. A commitment to safety is a professional and organizational expectation, and being empowered to overcome safety-related challenges necessitates multilevel and interprofessional accountability.

Erin E Dorset, Scott K Sakaluk, Charles F Thompson
Predation is a significant cause of nest failure in passerine birds, and, thus, natural selection is expected to favor behavioral plasticity to allow birds to respond to perceived changes in predation risk. However, behavioral plasticity in response to perceived predation risk, and its potential fitness-related costs, are understudied. In a wild population of breeding house wrens (Troglodytes aedon), we tested the hypotheses that (1) birds show behavioral plasticity in response to perceived nest-predation risk to reduce self-risk or risk to offspring, but (2) this plasticity incurs fitness-related costs...

There has been limited community engagement in the burgeoning field of genomics research. In the wake of a new discovery of genetic variants that increase the risk of kidney failure and are almost unique to people of African ancestry, community and clinical leaders in Harlem, New York, formed a community board to inform the direction of related research. The board advised all aspects of a study to assess the impact of testing for these genetic variants at primary care sites that serve diverse populations, including explaining genetic risk to participants...

PURPOSE: Disordered eating is more prevalent among adolescents with attention deficit/hyperactivity disorder. Both inattention and hyperactivity/impulsivity symptoms show strong associations with disordered eating, but few investigations of these associations have been longitudinal. Thus, we examined the effect of childhood to adolescent inattention and hyperactivity/impulsivity symptom trajectories on late adolescent disordered eating. METHODS: We used growth mixture modeling to identify distinct inattention and hyperactivity/impulsivity symptom trajectories (called "classes") across three time points (ages 8-9, 13-14, and 16-17 years) in the Swedish Twin study of CHild and Adolescent Development...

Neuro-anatomical evidence supports the potential for threat-related factors, such as fear, anxiety and vigilance, to influence brainstem motor nuclei controlling eye movements, as well as the vestibular nuclei. However, little is known about how threat influences human ocular responses, such as eye saccades (ES), smooth pursuit eye tracking (SP), and optokinetic nystagmus (OKN), and whether these responses can be facilitated above normal baseline levels with a natural source of threat. This study was designed to examine the effects of height-induced postural threat on the gain of ES, SP and OKN responses in humans...

Azathioprine is an immunosuppressive drug that has shown effectiveness in inflammatory bowel disease treatment. Its metabolite, 6-mercaptopurine, is metabolized through thiopurine methyltransferase. Patients with low enzyme activity may have more frequent and severe side effects. The most common is leukopenia, and rarely pancytopenia. The thiopurine methyltransferase activity monitoring shows an individualized profile of enzymatic activity but it should not replace monitoring by performing serial blood counts...

Transposases are mobile genetic elements suggested to have an important role in bacterial genome plasticity and host adaptation but their transcriptional activity in natural bacterial communities is largely unexplored. Here we analyzed metagenomes and -transcriptomes of size fractionated (0.1-0.8, 0.8-3.0 and 3.0-200 μm) bacterial communities from the brackish Baltic Sea, and adjacent marine waters. The Baltic Sea transposase levels, up to 1.7% of bacterial genes and 2% of bacterial transcripts, were considerably higher than in marine waters and similar to levels reported for extreme environments...

AIM: To test whether muscle mass evaluated by creatinine excretion (EXCr) is maintained in patients with end-stage kidney disease (ESKD) treated by peritoneal dialysis (PD), we evaluated repeated measurements of EXCr in a PD population. METHODS: One hundred and sixty-six PD patients (94 male, 72 female) receiving the same PD dose for the duration of the study (up to approximately 2.5 years) had repeated determinations of total (in urine plus spent dialysate) 24-h EXCr (EXCr T) to assess the adequacy of PD by creatinine clearance...

It is widely accepted that cortical neurons are similarly more activated during waking and paradoxical sleep (PS, aka REM) than during slow wave sleep (SWS). However, we recently reported using Fos labeling that only a few limbic cortical structures including the retrosplenial (RSC) and anterior cingulate (ACA) cortices contain a large number of neurons activated during PS hypersomnia. Our aim in the present study was to record local field potentials (LFPs) and unit activity from these two structures across all vigilance states in freely moving male rats to determine whether the RSC and the ACA are electrophysiologically specifically active during basal PS episodes...

Alkenes are linear hydrocarbons with one or more double bonds. Despite their potential as biofuels and precursors for specialty chemicals, the underlying biochemistry and genetics of alkene biosynthesis in plants remain elusive. Here, we report on a screen of natural accessions of poplar (Populus trichocarpa) revealing that the leaf cuticular waxes are predominantly composed of alkanes and alkenes. Interestingly, the accumulation of alkenes increases with leaf development, is limited to the abaxial side of the leaf, and is impaired in a few accessions...

STUDY OBJECTIVES: Excessive daytime sleepiness (EDS) is a key symptom of obstructive sleep apnea (OSA). The Psychomotor Vigilance Task (PVT) has been suggested as an objective easy-to-use, inexpensive alternative to the Multiple Sleep Latency Test (MSLT) to measure EDS. In patients with OSA, physiological sleepiness, but not subjective EDS (Epworth Sleepiness Scale [ESS]), has been associated with increased levels of the sleep- inducing proinflammatory cytokine interleukin-6 (IL-6). The goal of this study was to assess the association of PVT with objectively measured sleepiness (MSLT) and subjectively measured sleepiness (ESS) and IL-6 levels in patients with OSA...

BACKGROUND: Despite the reduction in glycemic derangement in patients with type 1 diabetes mellitus (T1D) through dietary and therapeutic adjustments implemented before, during and after continuous exercise, evidence for its effectiveness with intermittent forms of exercise, such as soccer, is still lacking. METHODS/DESIGN: We designed a study protocol for a randomized, crossover, double-blinded, controlled trial, for the evaluation of the effect that a strategy of dietary and therapeutic modifications may have on safety and performance of persons with T1D in soccer training sessions and cognitive testing...

Individuals who work nonstandard schedules, such as rotating or night shifts, are more susceptible to workplace injuries, performance decrements, and reduced productivity. This population is also almost twice as likely to use illicit drugs as individuals working a standard day shift. The purpose of this study was to examine the effects of smoked marijuana on performance, mood, and sleep during simulated shift work. Ten experienced marijuana smokers completed this 23-day, within-participant residential study...

Despite psychobiography's long-standing history in the field of psychology, there has been relatively little discussion of ethical issues and guidelines in psychobiographical research. The Ethics Code of the American Psychological Association (APA) does not address psychobiography. The present article highlights the value of psychobiography to psychology, reviews the history and current status of psychobiography in the field, examines the relevance of existing APA General Principles and Ethical Standards to psychobiographical research, and introduces a best practice ethical decision-making model to assist psychologists working in psychobiography...
